摘　　要：对海面目标进行ISAR成像时,会受到海杂波的影响。基于海杂波的复合散射理论,分析了海杂波的统计分布模型、时间相关性和空间相关性。采用球不变随机过程产生时间和空间相关的相参K分布海杂波。对时间相关和空间相关性的引入方法进行了分析。最后设定仿真环境产生具有时间和空间相关的相参K分布二维海杂波,结果表明了该方法的有效性。When an inverse synthetic radar （ISAR） imaging the target On the sea, sea clutter may influence the imaging performance. Based on theory of compound scatter, the amplitude distribution, temporal correlation and spatial correlation were discussed here. The simulation model of temporal - spatial correlated coherent K - distributed clutter is estimated using SIRP. The introduction of introduction of temporal correlation and spatial correlation in sea clutter simulation were analyzed. Coherent K- distributed sea clutter was simulated under the certain conditions. The validity of this method is proved by simulated results.
