Target detection with single surveillance channel for PBR

In this study, the target detection based on single surveillance channel is proposed in passive bistatic radar (PBR) system. The reference signal is recovered from the covariance matrix. The cancellation performance of the recovered reference signal is further investigated, and the reason for the poor cancellation performance is also analyzed. In order to improve the performance, the maximization cancellation ratio (CA) criterion is designed, the whole processing is given. Finally, the effectiveness of the proposed scenario has been demonstrated by the real recorded data.
