Abstract:

The single look Interferometric synthetic aperture radar (InSAR) system is characterized by strong anti-interference capability. The interferometric phase of the interference signal is constant in the fast time domain, and remains nearly the same in the slow time domain, thus one jammer only is invalid in the active deception of an InSAR. This paper proposes a deception jamming method against InSAR using two(multi) jammers. The deceptive single look complex InSAR images (the interferograms) can be decomposed into two complex SAR components, and the interference signals of the two jammers are achieved from each component. A model of the deception jamming against InSAR is given, and the false-target templates and the steps in generating interference signals are studied. The estimation method and the effect of the error of InSAR parameters on the InSAR processing of the interference signals are analyzed. Theoretical analysis shows that the method is effective in the deception of both SAR 2-D images and InSAR 3-D images.
