N2 - It is important to get a high-quality reference signal for the cancellation and correlation detection in passive radar. The single frequency network (SFN) configuration of transmitters will cause the interference in the reference channel. The infinite impulse response filter based on the normalized least mean square rule (IIR-NLMS) can improve the cancellation gain and signal noise ratio (SNR) of the target echo, but it has limited capability in suppressing co-channel interference. In order to solve this problem, a type of equalization filter is proposed, and then combining with the IIR-NLMS filter, the equalization IIR-NLMS filter is obtained. Simulation results verify the efficiency of the algorithm.
