description In this paper, we compare and contrast code, time and spatial domain signal processing techniques for mitigating the effects of the ambiguities present in single frequency network digital broadcast signals in passive radar. By performing these additional processing steps, the number of ambiguities present in the range Doppler scene will be reduced by approximately one third or a half (situation dependant). We also compare and contrast different combinations of temporal and spatial signal processing and demonstrate using real data that adaptive beamforming combined with temporal signal processing gives the greatest SINR performance.
