摘要 给出了K分布海杂波概率分布特性、时间相关特性分析和空间相关特性分析,结合球不变随机过程(SIRP),提出了一种生成时空相关K分布海杂波的仿真方法,并对其时间相关特性、空间相关特性进行了理论分析和仿真。结果表明,该方法能够生成满足要求的时空相关K分布杂波序列,生成杂波序列的概率密度函数(PDF)和功率谱密度与理想的K分布海杂波吻合较好。 The probability distribution feature,temporal correlation feature and spatial correlation feature analysis for K-distributed sea clutter were given,and then a model of temporal-spatial correlated K-distributed sea clutter was proposed combining spherically invariant random processes.Results demonstrate that this method can generate K-distributed sea clutter satisfying the given temporal-spatial correlation properties,and probability density function and power spectrum density of the generated clutter accord with that of the ideal K-distributed clutter.
