中文说明：K分布适用于描述高分辨雷达的非均匀杂波，多用于对海杂波的模拟。 ISAR是一种相干雷达，其海杂波必然是相干且时空相关的。对于相干相关杂波，以往的方法都是将非相干的ZMNL方法加以推广得到相干的ZMNL模型。这种方法得以应用的一个前提是已知非线性变换前后杂波相关系数的非线性关系，然而对于相干相关K分布杂波却很难找到这样一种非线性变换，于是我们采取SIRP方法来仿真ISAR的海杂波。
English Description：
K Distribution can be used to describe the non-uniform clutter of high resolution radar, and is mostly used to simulate the sea clutter. ISAR is a coherent radar, and its sea clutter must be coherent and spatiotemporal correlated. For coherent correlated clutter, the previous methods are to extend the incoherent ZMNL method to obtain the coherent ZMNL model. One of the preconditions for the application of this method is to know the nonlinear relationship between the clutter correlation coefficients before and after the nonlinear transformation. However, it is difficult to find such a nonlinear transformation for coherent correlated K-distributed clutter, so we adopt SIRP method to simulate the sea clutter of ISAR.
