| 摘 要： | 雷达杂波特性可以用幅度分布特性和频谱分布特性来描述,文章利用无记忆非线性变换(ZMNL)进行建模仿真,产生具有高斯谱的相关K分布杂波;详细介绍了仿真建模的具体过程,并验证了仿真结果;结果表明,此方法能更快速准确地模拟高分辨近距离雷达杂波,仿真得到的杂波序列可以直接用于雷达杂波模拟器中的输入信号。

| Abstract: | Statistical characterization of radar clutter can be described by the probability density functions and frequency spectrum of its samples.The method of zero memory nonlinearity(ZMNL) transform is used to generate the correlated K-distributed clutter.The process of modeling and simulating of K-distributed clutter is introduced and the result is shown.The obtained result proves that the presented method has high speed and accuracy in simulating high-resolution short-range radar clutter.The generated signal can be used in the simulation of radar systems. |
