| 摘 要： | 讨论了基于子波变换的抑制低频杂波成分的子波恒虚警处理,抑制高频杂波成分的子波浮动阈值处理和能够同时对杂波的低频成分和高频成分进行抑制的混合杂波处理方法,给出了三种处理模型和相应的杂波处理效果.通过对瑞利杂波和韦布尔杂波的子波系数的统计分布特性与零均值高斯杂波子波系数统计特性进行比较,说明该方法对非平稳分布的雷达杂波的处理具有很好的适应性.

| Abstract: | Radar clutter showed non-smooth statistic characteristic,so it was difficult to suppress it.The author mainly discussed the methods of the CFAR radar clutter processing based on wavelet transform technology used to suppress the low-frequency clutter,the floating threshold clutter processing used to suppress high-frequency clutter,and the mix processing method could suppress low-frequency part and high-frequency part simultaneously.The thesis provided three processing models and the clutter processing results.By statistical analysis on the wavelet coefficients of Rayleigh clutter and Webull clutter in comparison with the Gaussian clutter wavelet coefficients statistic characteristic,the result shows that this method is very applicable for suppressing the non-smooth distribution radar clutter. |
