A NEW HYBRID METHOD FOR SYNTHETIC APERTURE RADAR DECEPTIVE JAMMING

Jamal Saeedi

ABSTRACT

Based on the synthetic aperture radar (SAR) geometric model, a novel, and fast algorithm of large scene deceptive jamming against different SAR systems is proposed. First, a template deceptive image is transformed into the time domain signal using inverse image formation algorithm. Then, the transformed signal is convolved with enemy’s received SAR signal in order to cope with electronic countercountermeasures (ECCM) techniques. Finally, the generated jamming signal is transmitted to enemy’s SAR system for deceptive purpose. Specifically, we have proposed a hybrid method for SAR jamming, which uses a digital radio frequency memory (DRFM) system incorporating with SAR raw data simulation module. The experimental results for the proposed deceptive jammer demonstrate its ability to deceive SAR system.
