Waveform Selection of Active Radar Seeker for Anti Corner Reflector Interference
Corner reflector interference is a common passive interference faced by active radar seeker. Therefore, the anti interference method is an important supporting technology for active radar seeker of anti radiation missile to precisely attack the target. A waveform selection based method is proposed for radar seeker to counter the corner reflector interference. Firstly, a brief analysis is made of the radar characteristics of corner reflector, and then a criterion of maximum information distance is proposed as the criterion for waveform selection. The principle is as follows: in the case that radar launches LFM (Linear Frequency Modulation) signal, SF LFM (Stepped Frequency Linear Frequency Modulation) signal and BPSK (Binary Phase Shift Keying) signal, take the maximum information distance between the attacked target and one dimension high resolution range profile of the corner reflector as the optimal function, select one of the three signals to distinguish the target and corner reflector, thus to realize anti corner reflector interference. Simulation results show that the proposed algorithm has good performance.
