A Deceptive Jamming Against High and Low Orbit Bistatic SAR Using Frequency Diversity Array

Abstract

This paper proposes a method against bi-static synthetic aperture radar (SAR) jamming based on frequency diversity array (FDA). Firstly, we present the geometry model of the jamming signal of FDA-bistatic SAR. Then, we introduce two-dimensional non-uniform fast Fourier transform (2D-NUFFT) for FDA-bistatic SAR jamming imaging. Via simulation results, we find that the FDA has deceptive jamming effect on bi-static SAR.
