Abstract:High-Resolution Radar (HRR) range profiles provide a means to improve a GMTI tracker's performance when vehicles enter kinematically ambiguous situations. There is a need for methods that process HRR profiles on-the-fly, enhance their features, discover the salient features, and learn robust… more
Abstract:ALPHATECH proposes to develop a modular system for building and evaluating autonomous multi-sensor geo-registration technologies based on a rigorous mathematical framework and the utilization of a multi-attribute geospatial database. The multi-sensor geo-registration problem is an estimation… more
Abstract:Advanced optimization-based algorithms for sensor resource management have been previously developed to support Level 1 sensor data fusion (object or track-level) estimates. In the proposed effort, ALPHATECH will further develop a computational framework that can be used to represent the expected… more
Abstract:An essential capability of an information gathering architecture is the ability to adapt to dynamic re-tasking requirements (i.e. the ability to manage real-time moding, pointing, and directing of ISR sensors) commensurate with the decision-making time scale of tactical, battlefield operations. … more
Abstract:Maintaining continuous track of high-value ground targets in complex environments presents challenges for which use of complementary sensors offers a solution. A significant problem is targets moving in and out of hide sites, where track is lost and identification of targets emerging from hide is… more
Abstract:We propose a methodology for improving perfomrance of ATR and tracking algorithms. We discover and develop high-value features and templates extracted from multi-sensor and multi-look data, and enhance their utility using model-based and learing-based feature level fusion (and hypothesis level… more
Abstract:Surveillance technologies required for the successful prosecution of time-critical targets (TCTs) include detection, tracking, identification (ID), sensor resource management (SRM), and battle damage assessment. Because SCUD TELs are rarely stationary while in the open, moving-target ID is a… more
Abstract:Ground target tracking performance can be improved through the use of appropriately collected target signatures. In particular, associating reports and tracks is especially enhanced in dense target environments and move-stop-move scenarios. To support association, the signatures need to be collected… more

The RADR testbed will ingest satellite payload,… more
Abstract:We propose an end-to-end video-based system for online class recognition of moving vehicles observed by a passive stationary camera. SAVOR (or System for Automated Video-based Object Recognition) continuously detects, tracks, and classifies vehicles within the camera's field of view in real time,… more
Abstract:The development of inexpensive unmanned aircraft will soon bring the opportunity to place persistent organic hovering sensors at key locations in support of intelligence gathering, targeting, and force protection missions. As many of the sensor packages flown on these assets will be line-of-sight… more
Abstract:The goal of this SBIR is to develop a capability for securely transmitting cryptographic keys over wireless networking environments. The lack of perimeter defenses in wireless networks demands that all transmitters/receivers possess cryptographic devices to protect sensitive data. With the… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
