Abstract:
In the global system for mobile communication (GSM) based passive bistatic radar (PBR), there are not only strong interferences,which consist of direct signals from several base stations and strong multipath, but also a lot of weak interferences. So it is difficult to effectively suppress all interferences in GSM based PBR using only adaptive beamformer or low sidelobe technique. This paper proposes a method using two-step spatial filtering to suppress the interferences in GSM based PBR. First, the low sidelobe technique is used to suppress the weak interferences, and then the remained strong interferences are further suppressed by a robust adaptive beamformer. Finally, the performance of the proposed method is verified by simulation.
