信号失配对密集假目标干扰效果影响分析

Influence of signal mismatch on dense false target jamming effect

雷达干扰作战中,目标雷达的各项参数是未知的,干扰机采集到的雷达信号往往难以做到与雷达信号相匹配,所以必然存在失配情况下的干扰效果问题。主要分析干扰机采样信号与雷达信号在载频、脉宽和调制带宽三个方面失配条件下的密集假目标干扰效果,并通过仿真与试验验证了信号失配对密集假目标干扰效果的具体影响。

In radar jamming operations,the parameters of the target radar are unknown,and the radar signal collected by the jammer is often difficult to match the radar signal,so there must be a problem of interference ef fects in the case of mismatch.The jamming effect of jammer sampling signal and radar signal are mainly analyzed when they are mismatched in carrier frequency,pulse width and modulation bandwidth,and the specific effect of signal mismatching on jamming effect of dense false target is verified through simulation and test.
