SAR active-decoys jamming based on DRFM

The problem of how to realize the SAR active-decoys jamming is studied. Principles of the SAR active-decoys jamming are presented through analyzing range deception and azimuth deception, respectively. Thereby, two novel realization schemes are proposed. They can both realize active-decoys jamming effectively and only need measuring the angle between the radar and the jammer. The two realization schemes can be realized conveniently based on DRFM but they content the different deceptive demands respectively. Generally, we recommend the second one because it generates more decoys and it´s easier to realize. Their validities are proved by the simulated results.
