摘　　要：论述了合成孔径雷达（SAR）干扰的基本原理以及干扰技术的发展过程。介绍了研制的某SAR干扰对抗仿真系统，描述了该系统的构成及仿真流程，阐述了干扰仿真模块的功能及实现方法。在提高地面目标的生存能力，开展对SAR的对抗的前提下，针对包括连续波，转发，脉冲干扰等在内的多种干扰样式，研究了仿真系统对地面目标的戍像效果，对不同干扰样式的干扰效果进行了定量分析，并在不同的干信比条件下，对干扰效果进行了评估。不同战情条件下的仿真结果验证了该系统的有效性。The basic principles of SAR jamming and the development of jamming technique are discussed firstly. A simulation system to jam SAR is introduced in this paper. The constitution and simulation circuit of the system are described, and the functions and it~ realization method of the jamming simulation models are introduced. When the survivability of ground targets is enhanced and the SAR has been jammed, and aimed to many kinds of jamming modes such as continuous wave, retransmit and impulse interference, the imaging performance of the simulation system to ground targets is studied. The jamming effect under different jamming modes is analyzed quantitatively, and the jamming effect under different JSR is evaluated. Simulation results under different experimental condition demonstrate the effectiveness of the system.
