Detection of Moving Target in FM Broadcast-Based Passive Radar

Passive radar utilizes transmissions of opportunity to detect targets and estimate targets parameters. This paper systematically presents key techniques that concern the detection of moving targets in FM broadcast-based passive radar via ambiguity function. It addresses the common problems that exist in passive coherent radar, such as system design, interference cancellation and signal processing. Among which, the idea of automatic hardware cancellation is original. The efficacy of the proposed solution is demonstrated by offline processing real collected data sets.
