Abstract
In this paper, a high-vivid uniformly-moving target deception jamming method against synthetic aperture radar (SAR)-ground moving target indication (GMTI) based on inverse omega-k algorithm is proposed. In the method, the jammer's frequency response function is first derived for the uniformly-moving targets, which avoids the Fresnel approximation and has high accuracy. It achieves full focus even in the case of high squint angle and long synthetic aperture of radar. In addition, the efficient deception jamming is achieved by means of inverse omega-k algorithm, which significantly reduces the computation complexity. The experimental results indicate that the proposed method is effective to generate false uniformly-moving targets with high-fidelity against SAR-GMTI.
