Modeling and Characteristic Analysis for Air-Space Based Bistatic Radar

Air-space based bistatic radar is a new radar concept of space-based radar, has strong anti-jamming ability and can economize satellite payloads. However, given the fact that the transmitter and receiver of the radar system are placed on airplane platform and satellite platform respectively, the Doppler frequency is determined by two platforms, which makes the clutter characteristic more complicated. This paper considers the actual beam exposure range, establishes the clutter model of air-space based bistatic radar and analyzes the performance of space-time adaptive processing (STAP) in different configurations. Experiment results show that system performance is greatly influenced by configuration and that air-space based bistatic radar is feasible in certain configurations. This can provide references for the study of air-space based bistatic radar.
