Abstract :
Rebound jamming, a kind of main-beam jamming, is effective to resist BiSAR. Due to simultaneous coherence between interferences and target echoes in both down-range and cross-range, it is difficult to remove the interference from received signal. Based on the principle of two-channel cancellation using for moving target detection, the paper proposes a method to remove rebound jamming against BiSAR, which can give satisfactory interference cancellation when interference parameters are known either completely or partially. The estimation of interference parameters is presented, too. Validation is confirmed by simulations
