SAR多模干扰方法模拟研究

Study of Mixed Jamming Method for SAR

分析讨论了对合成孔径雷达进行多模式干扰的方法。首先分析、建立了SAR原始回波信号的数学模型,建立了有源压制干扰和欺骗干扰的信号模型,并且介绍了对于合成孔径雷达干扰的评估方法。最后结合提出的相关理论完成了对目标干扰的成像仿真实验,实验结果与理论分析相符,说明采用混合多模式干扰的方法可以被用来作为对抗SAR系统的一种有效手段。

The active and mixed jamming method of synthetic aperture radar was analyzed and discussed. The methods of noise and deceiving jamming and the signal model of transmitting were described. The raw echo signal of SAR and the model of jammed echo signal were expatiated, and the characteristic of SAR and the evaluating method of noise jamming were established. Finally, the noise jamming imaging of SAR was simulated. The results of simulation test accord with the theory analyzing, and they show that the mixed jamming method of SAR can be used in the researching of the countermove of SAR system.
