摘　　要：针对逆合成孔径雷达(ISAR)的干扰技术是雷达对抗领域的热点问题。该文提出一种基于多相位分段调制的干扰方法,对该调制方法的基本原理及其在信号脉内和脉间综合调制的过程进行详细分析,推导干扰信号在成像处理后的表达式,给出在2维上分别对干扰样式进行精确控制的参数设计方法,通过仿真验证相关干扰效果,说明应用该方法能够产生灵活可控的干扰样式和遮盖效果。The problem of ISAR image jamming is the main stream in radar countermeasures study. This paper proposes a new jamming technique for ISAR imaging based on Multiple Phase Sectionalized Modulation （MPSM） jamming method. Its basic principle and processing in intra-pulse and inter-pulse is analyzed in details. Then the final expression of MPSM jamming signal after ISAR imaging processing is derived, and the precise control method of jamming pattern by parameters design in double dimensions is provided. Simulation is conducted to prove the related jamming effects, and it is flexible and controllable to generate different jamming patterns and overspread effects by applying this new method.
