摘要: 双基SAR的收发分置使干扰系统对接收机难以准确定位，因此具有强抗干扰能力。该文分析了接收机不能精确定位情况下的欺骗式干扰性能，在双基SAR欺骗式干扰模型的基础上，研究了对双基SAR欺骗式干扰的散焦问题，通过理论分析，给出了可容忍散焦条件，由此可确定雷达接收机的允许设定范围并生成欺骗式干扰信号。仿真实验证实了理论分析的正确性。

Abstract: Bi-SAR system is characterized by strong anti-interference capability, this paper analyzes the deceptive jamming to the Bi-SAR with non-precision positioning receiver. The model of deceptive jamming against Bi-SAR is given, then the defocus issue of deceptive jamming is studied. Through theoretical analysis, it can ascertain the scope of the permission settings and generate the deceptive jamming signals under the condition of tolerable focus. Simulation results verify the correctness of the theory analysis. -
