Abstract :This paper presents the impact of channel errors for an FM based passive bistatic radar system mounted on mobile platforms for ground moving target indication insert ignore into journalissuearticles values(GMTI);. Reciprocal filter, which is effective compared to conventional matched filter insert ignore into journalissuearticles values(MF);, is performed for the pulse compression stage to remove the time-variant structure of the signal. The displaced phase centre antenna insert ignore into journalissuearticles values(DPCA); method is applied for the clutter cancellation and target detection. This technique is effective if the hardware is well calibrated. Thereby, the influences of calibration errors between the receiving channels are studied for different FM waveforms. The simulation results of the amplitude and phase errors are analysed separately.
