| 摘 要： | 提出了一种基于离散复线性空间加权范数的时空相关K分布杂波建模及仿真方法.该方法利用经典的零记忆非线性变换(ZMNL)法或球不变随机过程(SIRP)方法,生成时间相关的杂波序列,并对其进行归一化处理.通过线性变换矩阵,使一维的杂波转换成满足一定性质的二维序列,通过求解离散复线性空间加权范数最小值,对二维序列进行迭代修正并得到时空相关的杂波序列.通过理论推导证明了该二维序列满足时空二维杂波的时间相关性、空间相关性及幅度特性.仿真结果验证了该方法的正确性和可行性.

| Abstract: | A new method for modeling and simulation of temporal-spatial correlated K distributed clutter is proposed,based on weighted norm in discrete complex liner space.First,generate time-correlated clutter by the way of classic ZMNL or SIRP method;secondly,normalize the generated one-dimension clutter,then transform it into two-dimension clutter,which satisfy certain property,by liner matrix transformation;thirdly,iterate and improve the two-dimension clutter by solving the minimum weighted norm in discrete compl... |
