Since its creation in 2001, Wikipedia, the online and collaboratively produced encyclopedia, has become one of the most widely accessed Internet resources in the world. Wikipedia’s popularity, at least in part, is due to the amount of research being conducted via the Internet. In continued efforts to foster collaboration, technology transfer, and transparency, and to reduce duplication of effort, the Department of Defense (DoD) has launched its own wiki*: DoDTechipedia. WHAT IS DODTECHIPEDIA? DoDTechipedia is an online information wiki that contains encyclopedic information on numerous scientific and technical areas
fessionals and end users. Successful collaboration results in technological solutions and advancements, reduced costs, added capability through innovation, and reduced duplication of effort. DoDTechipedia is also designed to facilitate the rapid development of technology and innovative solutions to meet critical needs and fill technology gaps in support of defense operations. WHAT IS IN DODTECHIPEDIA? DoDTechipedia is set up much like the Wikipedia site it is modeled after. Each page has the navigation bar and search box on the left to allow users to easily navigate the wiki. Near the top of each page is a series of tabs that allows users to update the content on the page or view the history of the page. DoDTechipedia contains a variety of content including Technology Areas, Acronyms, Terminology, Interest Areas, Organizations, and related Technology Area Blogs. Technology Area Pages The primary focus of DoDTechipedia is the development of informative wiki pages on technology areas relevant to the DoD mission. The Technology Areas home page contains an expanded alphabetical index of all technology areas and their subtopics. Each top-level and sub-level topic is hyperlinked to allow the user to go directly to the topic of interest. The expanded index also serves as a quasi-taxonomy of DoD science and technology investment areas and enabling technologies of interest to the DoD.
relevant to the DoD mission and allows users to make contributions through adding, editing, and updating information. At the direction of the Director of Defense Research and Engineering (DDR&E), the Defense Technical Information Center (DTIC) launched DoDTechipedia in October 2008. Mission and Objectives The mission of DoDTechipedia is to facilitate the collaboration of DoD scientists, engineers, program managers, acquisition professionals and warfighters. The collaborative wiki is designed to create a forum for achieving this mission and enabling communication among these researchers, requirements developers, acquisition pro-
Country Pages Similar to Technology Area pages, Country Pages contain science and technology information. The difference, however, is the Country Pages focus on advances made by particular countries. Acronyms DoD is known for its extensive use of acronyms. To provide readers with a quick access resource, DoDTechipedia contains a section devoted to an extensive list of acronyms and the expanded notation of each acronym. These acronyms are linked to pages throughout DoDTechipedia by allowing the definition to be displayed when the cursor is hovered over a double underlined word.
DoDTechipedia Terminology Unmanned Vehicle: A powered vehicle that does not carry a human operator, can be operated autonomously or remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload. Ballistic or semi-ballistic vehicles, cruise missiles, artillery projectiles, torpedoes, mines, satellites, and unattended sensors (with no form of propulsion) are not considered unmanned vehicles. Unmanned vehicles are the primary component of unmanned systems.

Terminology For those unfamiliar with certain scientific and technical areas, a list of key words and terms are defined in the Terminology area. In addition to scientific and technical terms, the terminology page contains definitions for commonly used wiki terms, such as WikiGnome. Like Acronyms, certain terms included in pages throughout DoDTechipedia are linked to the Terminology area. Interest Areas The Interest Areas page is a forum for any user whether a program manager or a soldier overseas with a specific immediate or emerging technological interest or need, to post questions for the DoD Science and Technology (S&T) community. These Interest Areas represent technical challenges that the DoD faces in maintaining military readiness and effective mission capabilities. Links to relevant technology areas lead the user to some of the collaborative solutions that have been achieved or are in-progress. Organizations DoD is a massive entity with a large number of components, organizations, agencies, and affiliated programs involved with funding, researching, developing, testing, demonstrating, implementing, transitioning, procuring or managing science and technology. Listed on the main Organizations page of DoDTechipedia are those organizations directly as well as indirectly supporting DoD. Each organization has a link to a separate page which provides more detail. Blogs A web log, more commonly known as a blog, is a series of focused postings on a particular topic or subject. Blog postings are usually made by an individual who “owns” or maintains the topic or subject blog. In DoDTechipedia, blog postings are restricted to the “blog owners,” while blog comments are open to the entire

community. Postings are often commentaries on recent events, publications, announcements, or anything else relevant to the subject area. DoDTechipedia currently has more than 25 blogs on 4
Monitoring Marine Environments Networking Technology Networking Unmanned Vehicles Radar Robotics Sensor and Data Fusion Social Software Specialty Materials for Airships
Technology Areas of high interest to the DoD. These blogs are maintained by subject matter experts in the particular technology area. DoDTechipedia is always looking for additional “blog owners.” Other Features Since the content of DoDTechipedia is almost continuously being updated, the administrators of the wiki provide several other features to aid users in staying current with the information available. For example, users can opt to receive a triggered email when a particular page has been updated or created, a blog posting has been added, or a discussion item has been posted to a particular page or blog. Users can also receive a daily summary of all updates. In addition, the wiki allows users to store preferences such as favorite pages. Help, Frequently Asked Questions, a printable Job Aid, and Tutorial pages provide information to allow a user at any level of wiki experience to research, edit, or update content on DoDTechipedia. Guidelines give users boundaries in terms of what type of information is allowed and what is not allowed. Many of the Blog and Technology Area pages are conducive to active discussions about the topic. DoDTechipedia allows users to add comments or questions to the blog or page. In most cases where appropriate, if the comment or question is posted on a blog, the blog owner will respond. WHAT TECHNOLOGY AREAS DOES IT COVER? DoDTechipedia was initially populated using DDR&E’s strategic science and technology priorities, and the scientific and technical topics covered in DoDTechipedia continue to expand. Each area has multiple sub-topics that are increasingly specific, and are organized to create a taxonomy-like structure of technologies that are of particular interest or importance to the DoD scientific and technical community. A list of Technology Areas included in DoDTechipedia is listed on page 5. The wiki environment easily allows the topics and sub-topics to be reorganized to alter the taxonomy-like structure as DoDTechipedia matures. WHAT ARE THE BENEFITS? Since scientific advancement and technology development occurs through a vast array of DoD organizations, programs, and projects, a challenge commonly faced by the DoD community is the difficulty in keeping abreast of the advancements and developments that may be relevant and beneficial to other areas. DoDTechipedia is intended to eliminate some of these barriers and mitigate these types of challenges. The wiki environment enables the DoD community to more readily collaborate with private organizations on scientific advancements and technology development. As an approach without departmental barriers, DoDTechipedia also facilitates joint collaboration on R&D efforts between military services. This will help to overcome some of the traditional communication and coordination barriers that have inhibited cooperation in the past.

The last column lists the range of Pd values from a comparison of two airborne total field (TF) systems that were tested by the same sponsor in 2003 at a similar site approximately 50km from the 2007 site (see reference  for additional details). APPLICATIONS Airborne systems offer an alternative to ground-based (vehicletowed and man-portable) systems for evaluation of UXOcontaminated sites. Airborne systems typically are less sensitive than ground-based systems due to their greater stand-off distance between sensor and target, and a more contentious noise source (the helicopter). However, the airborne platform offers 4.7 data acquisition at rates of 4.5 4.2 4.0 hundreds of acres/day, com3.7 3.5 3.2 pared to tens of acres/day for 2.9 2.7 2.4 vehicle-towed systems and 2.2 40mm frag 1.9 1.7 several acres/day for man1.4 1.2 0.9 portable systems.

The responses of individual items have been measured as a function of orientation and standoff distance, and can be estimated. The viability of airborne systems for a particular site can be evaluated by using these estimates of ordnance response when the types of ordnance at the site are known, and where the flight height (constrained primarily by vegetation and topography) can be accurately estimated. Statistical tools have been developed to assist in planning and evaluating these surveys.[8, 9] 4426890

For small ordnance or large sensor stand-off distance, a conceptual framework for evaluating the density of closely-spaced items with an airborne magnetometer system has been developed. The study provides a rule of thumb for determining whether anomalies from two items will be discrete or overlapped. When working with vertical magnetic gradient data, the equivalent ratio of horizontal separation to sensor height above the target, referred to as the separation/height ratio (SHR), would predict anomalies to be overlapped for values of SHR <0.4, partially overlapped for 0.41.2. This relationship between SHR and overlap has proven consistent with results from closely-spaced blind-seeded items emplaced at the New Mexico test site. When items are sufficiently close together that their individual peaks cannot be resolved, their collective response simulates that of a horizontal sheet. If one can assume that all of the items are uniform in size and depth, then their density can be calculated from the peak magnetic response. If the density is sufficiently high, very small ordnance which would ordinarily be undetectable, become visible. Figure 4 shows an example of airborne data over simulated high-density targets. The 20mm cluster has a real density of 25 items per square meter and a calculated density of 23 items/m2. The 40mm cluster has a real density of four items/m2 and a calculated density of 1.8 items/m2. ELECTROMAGNETIC SYSTEMS Although UXO sites are present throughout the US and at many locations worldwide, there are many sites (e.g., New Mexico, California, Hawaii) where magnetometer systems, whether ground-based or airborne, are ineffective for ordnance detection because of high concentrations of basalt or other magnetic rock or soil types. Ground-based electromagnetic systems, such as the Geonics EM-61, are typically used at these sites, and have much better performance than magnetometer systems. In fact, electromagnetic systems are predominant in ground-based investigations for UXO at all sites, except Figure 5. The Battelle TEM-8 timewhere ordnance is expected domain electromagnetic system to be particularly deep. The development of airborne electromagnetic systems for UXO surveys is more complex than the corresponding magnetometer systems. Two prototype studies have led to development of an eight-channel time-domain system, known as the Battelle

TEM-8.[11, 12] The TEM-8 system (Figure 5) has a dual transmitter loop consisting of two 3m x 4m multiple turn loops and four 75cm x 20cm receiver coils mounted parallel to the long axis of each of the two transmitter loops. Preliminary results show that at altitudes of about one meter, the performance of the TEM-8 system is similar to that of magnetometer systems (Figure 6), and that joint interpretation of magnetic and electromagnetic datasets can reduce the numbers of false alarms. ONGOING RESEARCH A current study for the Strategic Environmental Research and Development Program (SERDP) is aimed at evaluating airborne frequency domain electromagnetic (FDEM) approaches for mapping and detection of UXO. The study will use modeling and ground testing to evaluate whether a FDEM system could outperform the existing airborne TEM-8 system. Multi-axis receiver coils are also under consideration. Further improvements in magnetometer systems will require additional, more compact sensors, possibly arranged to measure gradients in more dimensions. Another project, led by the Idaho National Laboratory (INL), is focused on developing an airborne system that can operate on an unmanned aerial vehicle. This represents a significant engineering challenge in order to operate safely and cost-effectively at the low altitudes required for UXO surveys. Although these systems were designed to address a particular need, they could be beneficial to a wide range of applications, perhaps extending beyond the environmental and engineering disciplines into other more traditional areas of geophysical study.

FCS ACTIVE PROTECTION SYSTEM IN ‘TOP 50’ INVENTIONS By John R. Guardiano
The Army’s new Active Protection System, which is designed to safeguard Soldiers and vehicles from incoming fire, has been named one of the best inventions of 2008 by Time magazine. “Think of [it] as Star Wars for Soldiers,” said Time magazine in its Nov. 10 edition. The APS “will automatically detect an incoming round and then launch a missile to destroy it, all within a split second.” The Army is developing APS as part of its Future Combat Systems ground-force modernization program. FCS is designed to bring Soldiers into the 21st century by equipping them with stateof-the-art vehicles, communication capabilities, sensors and protective systems. The APS is actually part of a more comprehensive “hit-avoidance system” that the Army is building into a suite of eight new FCS Manned Ground Vehicles types. This more comprehensive hit-avoidance system will give the Soldiers in the MGVs “full-scale 360-degree hemispherical protection,” said FCS Program Manager Maj. Gen. Charles A. Cartwright. Current Army vehicles lack this level of protection because, he said, they were designed more than a generation ago, before the information technology revolution of the past quarter-century. Metastasizing Threats According to the Army’s Training and Doctrine Command, American servicemen and women face a proliferating array of new and more sophisticated threats, which, if not addressed, will jeopardize American lives and mission success. “The threats are getting more dangerous,” said TRADOC’s Deputy Commanding General, Lt. Gen. Michael A. Vane. “Technology proliferation is creating a dangerous mix of state-of-the-art technology, radical extremists, and irregular tactics. “Future Combat Systems, the MGVs, the hitavoidance system, APS,” he added “these all will protect our Soldiers against a variety of changing threats and address current force limitations.” The Army’s Active Protection System is still in development, but has proven itself in live-fire testing. Hit-avoidance prototypes, moreover, are scheduled for delivery in 2011, said Maj. Lewis Phillips, assistant product manager. Current-Force Limitations In the meantime, elements of the FCS survivability system are being incorporated into current Army vehicles on a limited basis. Because of inherent design limitations due to their age, current Army vehicles cannot accommodate a comprehensive hit-avoidance system, officials said. In addition to being equipped with active protection, the new Army vehicles, or MGVs, also are being designed with an independent hull structure, in which armor is bolted onto the vehicle. This allows for frequent armor upgrades to accommodate technological advances. The armor on current-force vehicles, by contrast, is integrated throughout the structure of the vehicle. Current force vehicles, consequently, have a very limited ability to accommodate better and more modern armor protection, officials said.

IED Protection Current-force vehicles – the Abrams Tank, Bradley Fighting Vehicle, and Stryker Interim Armored Vehicle – also were not specifically designed to withstand attack from Improvised Explosive Devices. The new FCS vehicles, by contrast, are being designed with a v-shaped hull, specifically to help diffuse IED blasts. And the seating inside the MGVs will be suspended from the ceiling of the vehicle to further reduce the shock and trauma of an IED blast. Army officials said this is significant because, for many of America’s enemies, IEDs have become the weapon of choice. IED attacks, in fact, account for the majority of US casualties in Iraq and Afghanistan and are a leading cause of brain injury to American servicemen and women. By separating occupants from the floor of the vehicle, which absorbs the blast, Soldiers will suffer much less trauma and injury, Army officials said. Quick Kill The FCS Active Protection System is being developed by Raytheon. Raytheon won the contract from the FCS program after participating in an open competition that involved other key competitors and competitor systems. A team of 21 technical experts from various US government agencies, the Army and private-sector industry evaluated competing Active Protection Systems. According to the Government Accountability Office, the team reached “a clear consensus... [that] Raytheon’s Quick-Kill system was the best alternative.” Army officials said that one key advantage of the Raytheon APS is its vertical launch system, which protects against top-attack rounds. They said this gives Soldiers true 360-degree hemispherical protection. The FCS Active Protection System “is the only available vertical launch system that I’m aware of,” Lewis said. Other Active Protection Systems out on the market employ horizontal launch systems and thus do not provide total vehicular protection. A vertical launch system, Phillips said, allows for redundant protection from all sides of the vehicle. One countermeasure situated anywhere on the vehicle can defeat any incoming round. Horizontal launch systems lack this capability, Phillips said. (John Guardiano serves in the Plans Division of Army Public Affairs and is a frequent contributor to the Army News Service.)

ARMY BEEFS UP NON-LETHAL CAPABILITIES By Staff Sgt. Michael J. Carden
they have ways to actually deal with folks before they have to result to lethal force. The whole focus is to provide Soldiers with more options before they have to use lethal force.” 10th Mountain Division’s 2nd and 3rd Brigade Combat Teams were the seventh and eighth brigades to receive the set. The set was produced by the Program Executive Office Ammunition and costs just more than $1 million. Fielding began in July to units getting ready for deployment. Every brigade combat team and military police brigade is expected to have the issue in about 18 months, officials said.
Soldiers are trained to use non-lethal force as much as possible. But until recently, not every Soldier had “the right mix” of tools and capabilities to meet those goals, an officer said during exercises here last week. “The more capabilities we give the Soldiers to operate in the non-lethal realm, the less likely they’re going to have to resort to lethal force,” said Army Maj. Thomas Aarsen, a close combat systems project officer for the Defense Department’s Program Executive Office Ammunition. “[The Army] has been asking Soldiers to do this for a long time, but now they have the tools to do so,” Aarsen said during a Non-Lethal Capabilities Set fielding and training for two 10th Mountain Division brigade combat teams. The Army has been improving its non-lethal capabilities since Jeff Teats, right, a non-lethal 2000 in response to US actions in Kosovo. The Army needed someweapons instructor, observes thing to use before resorting to lethal force, Aarsen said. There were Spc. Yevgeniy Popov, a chemical variations of non-lethal packages before. But until now, there hasn’t warfare specialist assigned to the 10th Mountain Division’s been a system available to Soldiers with the amount of tools the latHeadquarters Company, est set provides, Aarsen said. “Non-lethal capabilities has definitely 3rd Special Troops Battalion, been an evolving process,” he said. “Technology and equipment con3rd Brigade Combat Team, fire a tinues to keep getting better, and we continue to keep learning more Taser during non-lethal weapons and becoming more innovative. I think now we have about the right training on Fort Drum, NY, Nov. 19, 2008. Photo by Staff mix of what the brigades will need. Though there may be times when Sgt. Michael J. Carden they need more or less, it‘s a good solution at this point.” The fielding, an Army requirement, consists of five modules and comes with a weeklong training on its capabilities and uses, Aarsen said. The modules are based on tactical situations including checkpoint manning, convoy operations, detainee operations, crowd control and dismounted patrols. A Taser package sub-module with 18 Tasers and holsters also comes with the set, he said. Instructors from the Army’s military police school at Fort Leonard Wood, Missouri., who developed the training curriculum, travel to the gaining unit’s installation to train the Soldiers. During the course, soldiers fire non-lethal ammunitions, such as Tasers and shotgun and grenade launcher rounds filled with rubber pellets. Soldiers also learn to use the different modules to the Soldiers, assigned to the 10th Mountain Division, capacity that they can teach their squads and plalearn uses and techniques of a spike-strip net toons what they’ve learned, Aarsen said. The during non-lethal capabilities training on Fort equipment includes audio-translating devices and Drum, NY. Photo by Staff Sgt. Michael J. Carden the portable vehicle arrest barrier, he added. The voice response translator is a hand-held electronic device that can be synced to eight users’ voices and translate more than 350 phrases in 18 languages. Soldiers can use it to communicate in Arabic, Farsi, Urdu and Pashtun, for example, without an interpreter, Aarsen said.
