摘　　要：目前国内外尚未开展对步进频率逆合成孔径雷达的欺骗干扰研究。根据步进频率逆合成孔径雷达成像原理,提出了对步进频率ISAR进行有源欺骗干扰的假目标信号合成方法,利用该方法得到的假目标具有运动状态可控的优点。文中详细给出了合成假目标信号的理论表达式、算法流程、及用来产生假目标信号的步进频率ISAR图像合成器的系统结构。进行了假目标图像合成的仿真实验,并进行了对步进频率ISAR的欺骗干扰仿真实验。仿真结果证明了所提出假目标信号合成方法的有效性和可行性,利用提出假目标信号合成方法得到的假目标成功实现了对步进频率ISAR的欺骗干扰。The study of deception jamming against stepped-frequency ISAR hasn＇t been done at home and abroad yet. A method of producing false targets for countering stepped-frequency ISAR is proposed. Also, the image synthesis method proposed has the advantage that false target motion states can be controlled or adjusted. The principle, system architecture and theoretical foundation of the image synthesizer against stepped frequency ISAR are described in detail in this paper. Furthermore, simulations have been done, and the deceiving jamming simulation against stepped-frequency ISAR is also done. The simulation results show the effectiveness and feasibility of the method, and the the deceiving jamming against stepped-frequency ISAR is successfully accomplishod.
