2005
The Air Force Research Laboratory Information Directorate (AFRL/IF), under sponsorship of the Department of Justice's (DOJ), National Institute of Justice (NIJ) Office of Science and Technology (OST and portable, personal computer (PC) based standoff systems to enable the determination of events during critical incident situations. The technologies utilized are primarily focused on active radars operating in the UHF, L, S (ultra wideband (UWB)), X, and Ku Bands. The data displayed by these systems is indicative of range (1 Dimension), or range and azimuth (2 Dimensions) to the moving individual(s). This paper will highlight the technologies employed in five (5) prototype TWS systems delivered to NIJ and AFRL/IF for test and evaluation. It will discuss the systems backgrounds, applications, current states of evolution, and future plans for enhanced assessment.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
