| 摘 要： | 常规SAR和双基SAR的不同在于双基SAR收发分置,接收机往往很隐蔽,使得双基SAR具有强抗干扰性能。现有的对双基SAR的干扰都是基于已知接收机的准确位置。在接收机定位不准确的情况下分析了双基SAR欺骗式干扰。在欺骗式干扰模型的基础上,从方位向脉冲压缩方面考虑,研究了欺骗式干扰的散焦问题。通过理论分析和仿真,给出了双基SAR接收机可容忍散焦范围准则,由此可以确定雷达接收机的允许设定范围,将接收机设定在此范围内欺骗干扰仍能成功。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 different from common SAR.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 azimuth pulse compression.Through theoretical analysis and a lot of simulations,it can ascertain the scope of the permission settings and generate the deceptive jamming signals under the condition of to... |
