This paper addresses the problem of a passive radar system mounted on a moving platform with the purpose of Ground Moving Target Indication (GMTI). When exploiting digital communication signals for passive radar, the signal structures result in ambiguities and grating-lobes which may overlap echo signals of targets, which are then difficult to detect. Echo signals of targets can also be covered by Doppler-shift induced from the receiver's motion. We suggest to apply a reciprocal filter for ambiguities removal and the Displaced-Phase Centre-Antenna (DPCA) technique for clutter removal. The effectiveness of our approach is shown with simulated and real data.
