Research on Electronic Camouflage Jamming Technology Based on Compensating Modulation

ISAR is a kind of new microwave imaging system,which is the one of important perspective of imaging radar.Because of its imaging via two-dimension compress(range and cross-range compress),its anti-jamming capability is stronger than that of traditional radars.Aimed at chirp ISAR,a new electronic camouflage jamming method is proposed in this paper.In the method,on the basis of obtaining transmitted signal of opposite side,the phase compensating modulation can be utilized to simulate returned signal of any scatterer of the target.The camouflage jamming can be achieved via retransmitting simulated echo.The effectiveness of the proposed method can be proved by simulation results.
