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.

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 complex liner space. The proposed method is proved by theoretical derivation that the generated sequence satisfies the property of temporal-spatial clutter, which has certain time correlation, spatial correlation and amplitude. Finally, computer simulation proves the validity and feasibility of the model.
