相关K分布杂波的建模与仿真

Modeling and simulation of Correlated K-distributed Clutter

本文讨论了相关K分布杂波的建模仿真。K分布杂波过程的统计信息可以用两个部分来表征，即快变化分量和慢变化分量，在K分布的自相关函数与高斯分布的自相关函数之间的非线性关系的基础上，利用修正的无记忆非线性变换法（ZMNL），产生了相关K分布随机序列。仿真结果证明了这种方法的有效性。

In this paper modeling and simulation of correlated K-distributed clutter was discssed. The statistical information of K-distributed clutter may be described by two parts-the 'speckle' part and modulated part. The correlated K-distributed random sequences were generated by modifie zero metnry nonlinearity (MZMNL) on the base of the autocorrelated function nonlinearity relation between K-distribution and Gaussain.Simulated results proved the validity of this scheme.
