Abstract
For TV/FM based passive bistatic radar (PBR), due to the narrow bandwidth and low frequency of the transmitted signal, there are usually multiple targets located in the same range-Doppler bin, so it is necessary to carry out multi-target DOA estimation. This paper proposed a method of multi-target DOA estimation based on sparse reconstruction for TV/FM PBR. At first, clutter cancellation algorithm and range-Doppler cross correlation are utilized to remove DMC and improve SNR of targets. In order to acquire targets' DOA, signals in targets ‘range-Doppler bin are then reconstructed in spatial domain using sparse reconstruction algorithm. Finally, the performance of this method is studied using numerical simulation.
