摘要
数据后处理雷达通过对接收到的回波信号进行数据分析处理,提取真实目标和欺骗干扰信号的幅度起伏差异,实现对欺骗干扰信号的检测和抑制。为了破坏数据后处理雷达在幅度域的抗干扰能力,对雷达回波信号进行分析处理,在产生欺骗干扰的基础上,进一步对其进行幅度控制,产生幅度上与目标回波也相关的欺骗干扰。仿真结果表明该方法对数据后处理雷达有很好的干扰效果。
The anti-jamming radar can detect and inhibit the deception jamming signal in data processing, according to the difference of the amplitude fluctuation between the real targets and deception jamming. In order to interfere with this type of the radar, a method for controlling the amplitude of the deception jamming is proposed, after analyzing the radar signal echo. Finally, compared with the deception jamming signal whose amplitude is not controlled, the simulation results show that the proposed method performs well against the data processing radar.
