摘要
Abstract
By adjusting parameters such as rotational angular velocity and rotational radius,micro-Doppler modulation on the echo signals of synthetic aperture radar(SAR)can be generated by rotating corner reflectors,facilitating the generation of various jam-ming effects.In this paper,a novel passive jamming method for SAR systems is proposed,which is based on the rotating corner re-flector.The proposed method sets the rotation center of the corner reflector to perform circular motion around a specific rotation center while also performing circular motion around another center point.An imaging model of the rotating corner reflector is estab-lished by employing the range-Doppler algorithm and the jamming parameters are analyzed.The regulatory impacts of different pa-rameters on the jamming effectiveness of the proposed method are quantitatively discussed,and the jamming patterns generated un-der various modulation parameters are verified and analyzed.Additionally,the feasibility of achieving large-scale barrage jamming by means of the corner reflector array is explored.Simulation results verify the correctness of the theoretical analysis,which can provide a foundation for the application and implementation of this method.关键词
