摘　　要：逆合成孔径雷达(ISAR)是一种高性能的成像雷达,其工作机理和作战使用都与常规体制雷达有着很大的不同,在分析ISAR成像原理的基础上重点研究了噪声压制干扰对ISAR成像的影响,并建立了ISAR系统的干扰仿真模型,针对噪声调频信号进行了干扰仿真实验,给出了不同信噪比下的仿真结果,仿真结果表明了干扰方法的可行性和有效性。Inverse synthetic aperture radar （ISAR） is one kind of imaging radar with high capability. It has big difference from common radar in work mechanism and the use of campaign. The influence of noise barrage jamming on ISAR on the base of analyzing the imaging principle of ISAR was studied and the simulation model of ISAR was built, the noise FM jamming experiment is carried out and the simulation results with different SNR are given at the same time, The results of simulation prove the jamming method is corrective and effective.
