Movements of the human body provide characteristic RF features that provide information on the location of human limbs and joints, as well as human body orientation and direction of travel. Properly interpreting these signatures within the radar returns will enable the generation of virtual renderings of human posture and orientation signatures of the detected human using STTW radar measurements. It is the objective of this proposed research and development effort to exploit these subtle dynamic micro-Doppler and instantaneous frequency features and to develop the algorithms for real-time display of virtual images of the interpreted radar returns. Similarly, inanimate objects will be imaged using UWB high resolution SAR techniques similar to those currently being used in ongoing sense through the wall radar developments. Benefits: The technology from this STTR effort will become instrumental in the development of a variety of military and commercial radar applications, including those requiring through the wall object detection, orientation and identification, especially the Transparent Urban Structures enabling capability program. The framework of this modeling and simulation technology also promises to have direct applicability to commercial applications, as well. This technology is directly applicable to civilian law enforcement, fire and earthquake disaster search efforts, security systems and Homeland Defense applications. Return
