An analogue TV signal-based passive radar onboard single air-platform can be considered as a bistatic CW radar. This implementation suffers, however, considerable range ambiguities due to the time-varying form of analogue TV video signal, when it detects and tracks the target by exploiting the AOA and TDOA information in echoes of targets from transmitter of opportunity. In this paper we describe the implementation of passive radar onboard single air-platform that measures the AOA information in the echoes of target using air-borne orthogonal interferometry array and obtains un-ambiguous TDOA information by exploiting both analogue TV video and audio signals.
