摘　　要：提出了一种全新的相干K分布杂波模拟方法。相比经典的零记忆非线性变换(ZMNL)和球不变随机过程(SIRP)法,该方法的优点是能产生自相关函数(ACF)为任意复数的杂波序列,且不需要进行矩阵求逆和非线性变换,运算速度得到显著改善。仿真结果证明了这种方法的有效性。A new method for modeling and simulation of coherent k-distributed clutter is presented. Compared with ZMNL and SIRP, this method can generate coherent clutter with arbitrary complex ACF, and it doesn＇t need resolving non-liner equation and matrix inverse. As a result the speed of simulation is improved markedly. The results from simulation prove the validity of this scheme.
