Passive Bistatic Denial with Waveform Diverse Array Radar

In this paper, the passive bistatic denial capability of waveform diverse array radar, such as multiple-input multiple-output (MIMO) radar and frequency diverse array (FDA) radar, is analyzed. It is revealed that the anisotropic transmitted signals of those two radar illuminators result in a mismatch between the target echo received by the passive bistatic radar (PBR) system and the reference signal estimated from the direct-path signal, which indicates that those two radar illuminators can achieve passive bistatic denial. Then, the denial performance of those two radar illuminators is analyzed and compared. Simulation results verify the effectiveness of the passive bistatic denial of MIMO radar and FDA radar.
