Research on Rebound Jamming Against BiSAR
-
摘要: 该文针对双基地SAR不同于常规SAR的工作方式，对双基地SAR弹射式干扰进行了研究，表明弹射式干扰可以有效地应用于双基地SAR的对抗。文中给出了双基地SAR弹射式干扰的信号模型，分析了固定转发时延弹射式干扰的原理和干扰效果，并研究了不散焦保护区与雷达参数的关系。计算机仿真验证了理论分析的正确性。

Abstract: Because of different working ways between BiSAR and SAR, this paper analyzes the feasibility of rebound jamming against BiSAR and the effective of the jamming is proved. The model of rebound jamming against BiSAR is given. The jamming principle and effect are described. As for Normal Rebound Jamming (NRJ), the paper analyzes the focus protection area. Theoretic analysis is verified via computer simulations. -
