针对密集假目标的干扰效果分析与优化

Effect Analysis and Optimization of Dense False Target Jamming Scheme

针对密集假目标干扰样式,在干信比较低的情况下,对雷达恒虚警检测处理方法和滑窗长度不同时的干扰效果进行分析与仿真。在此基础上提出一种两机协同的干扰方法,通过卷积灵巧噪声提高假目标间隔中的噪声功率,实现在滑窗长度未知情况下始终能够实现对目标信号的良好压制。

The jamming effect of the dense false target jamming scheme in low JSR conditions is analyzed and simulated in terms of different radar CFAR processing approaches and sliding window length.Based on the analysis results,a jamming method using two cooperative jammers is proposed.The noise power between false targets is improved using convolutional smart noise.In this way,the target signal can always be suppressed effectively when the sliding window length is unknown.
