摘要
本文分析讨论了对合成孔径雷达进行主动有源压制干扰的方法。文中首先简要分析了对合成孔径雷达进行有效干扰的工作方式和信号形式,并且分析了SAR原始回波信号的模式和受干扰信号模型,介绍了对于合成孔径雷达干扰的评估方法。最后结合文中提出的相关理论完成了对目标干扰的成像仿真实验。
The active and barrage-type noise jamming method of synthetic aperture radar is analyzed and discussed, The methods of noise jamming and the signal model of transmitting is described, The raw echo signal of SAR and the model of jammed echo signal are expatiated, the characteristic of SAR and the evaluating method of noise jamming are established. Finally, the noise jamming imaging of SAR is simulated.
