Target Detection in FM-Based Passive Radars in the Presence of Interference Signals in Reference Channel

In this paper, we examine target detection in FM-based passive bistatic radars (FBPBRs) in the presence of interference signals received in the reference channel of these systems. To do so, we propose a new signal conditioning algorithm to remove interference signals form the reference channel. Simulation results show that the proposed signal conditioning algorithm outperform the one presented in [1]. In addition to this, we evaluate the detection performance of cell averaging (CA) detector in the surveillance channel of an FBPBR in the presence of interference signals with exponential power spectral density. In this case, simulation results show that the proposed detection algorithm provides at least 11dB improvement when compared with its counterpart.
