雷达相干相关杂波的产生多是由相应的非相干相关杂波的零记忆非线性变换法(Zero Memory Nonlinearity,ZMNL)加以推广得到的。ZMNL法的前提是已知非线性变换前后杂波的相关系数之间的非线性关系,而对于相干相关K分布杂波却难以找到这样一种适用的非线性关系,于是提出了于不变随机过程法(Spherically Invariant Random Processes,SIRP)的相干相关K分布杂波的仿真模型,以高新型谱为例进行了仿真,仿真结果证明了这种方法的有效性。

[Abstract]
Coherent correlation radar clutter is mostly generated by extending zero memory nonlinearity (ZMNL) for corresponding incoherent coefficients clutter. The premise of ZMNL is the nonlinear relation between the correlation coeficients before and after nonlinear transform is known. But for the coherent correlation tributed clutter, such a nonlinear relation is difficult to find. In this paper, the simulation model of coherent correlation K distributed clutter using spherically invariant random processes (SIRP) is presented and as an example, the Gaussian spectrum clutter is simulated the results proved the validity of this scheme.
