二、利用零记忆非线性变换法实现机载相控阵雷达常规脉冲情况下的瑞利分布、韦伯尔分布的地面杂波模拟。 - This paper comprises two parts : radar clutter simulation and adaptive moving target indication . in the former part , we analyse the generation mechanism of single - channel radar correlated clutter and illuminate the simulated modeling way of rayleigh , log - norm , wei bull , k - distributed clutter with special power spetrum . all these models are used into the practical simulation of ground clutter , cloud - rain clutter and chaff jammer according to their features
在雷达杂波仿真部分分析杂波的产生尤其是单通道相关雷达杂波产生的机理，具体阐明了在指定杂波功率谱情况下，幅度服从瑞利分布、对数正态分布、韦伯分布和k -分布的杂波的建模与仿真方法，并根据不同分布的特点，将其应用到地杂波、气象杂波和箔条干扰的仿真中。 - Through the i 、 q component of ipix radar sea clutter data " s histogram analyses and by skewness and kurtosis computed , it is been shown that sea clutter amplitude is not rayleigh distribution ; through the comparison of amplitude histogram and distributed models with the same parameters , it is been shown that hh polarization clutter is lognormal distribution , whereas vv polarization is k - distribution ; at the same time the correlation function and power spectrum density are been analyzed , at last the correlation compound k - distribution stochastic sequences whose covariance matrix is been given are been generated through sirp algorithm
文中先介绍了海杂波幅度的有关模型,通过对ipix雷达海杂波数据的i 、 q分量的直方图以及倾斜度和峰度进行了分析和计算,证明了海杂波幅度不服从瑞利分布;使用幅度直方图和相同参数下的各种分布模型进行比较,得出hh极化符合对数正态分布,而vv极化服从k -分布的结论;同时对海杂波的相关函数和功率谱进行了分析,最后使用sirp算法产生了给定协方差矩阵的相关复合k -分布随机序列。
