摘　　要：论述了干涉合成孔径雷达(InSAR)干扰的基本原理,分析了InSAR成像的薄弱之处,设计开发了InSAR干扰仿真系统,并详细介绍了仿真系统的各个模块功能。仿真系统能够进行三维地形和回波模拟仿真,支持点、线、面、体4类干扰目标和8种干扰样式的生成。对在不同干扰样式下InSAR的成像过程以及成像结果进行了模拟仿真验证。详细介绍了仿真系统各模块的功能原理,并给出仿真实例进行论证。The basic principles of InSAR jamming are discussed,the weakness of InSAR imaging is analyzed,an InSAR jamming simulation system is developed,and the functions of the system modules are introduced in detail. By the system,3D terrains and echoes can be simulated, and four kinds of jamming targets including point, line, surface, and cubic targets as well as eight jamming patterns can be generated. In addition,the InSAR imaging processes and results of different jamming patterns are validated. Detailed description is given on the functions and principles of the modules,and a simulation example is provided.
