The method makes full use of the difference between the direction of deceptive jamming return and the direction of ground target return. Since DBF-SAR with range multiple apertures can improve the system freedoms, the direction of deceptive jamming are estimated through spectrum estimation algorithm. Then according to the estimated direction, the weighted coefficient is calculated to form the equivalent range antenna pattern. Since range antenna pattern has the nulls in the directions of interferences, deceptive jamming is suppressed through space filter. Simulation results show that range DBF-SAR system can counter deceptive jamming effectively and enhance imaging quality. %K Synthetic Aperture Radar (SAR) %K Deceptive jamming %K Digital BeamForming (DBF) %K Space filter %K Electronic Counter-Counter Measures (ECCM)
