Abstract : Passive radar systems employing illuminators of opportunity such as commercial television and FM radio signals instead of dedicated radar transmitters have been the subject of increasing interest over the past decade. Under the subject contract funds, components for a flexible passive radar testbed were purchased that allow the exploration of many different passive radar architectures over a wide range of frequencies, from the lower VHF TV band (around 50 MHz) to the lower cell phone band (almost to 1 GHz). Particular emphasis is placed on multiple-antenna passive radar systems employing beamforming, i.e. not just two-antenna interferometry, since beamforming passive radar systems have not been previously explored in academic settings. Extensive technical detail on the components is given, so that this report may also serve as a user's manual for the system.
