摘要
零记忆非线性变换法(Zero Memory Nonlinearity)和球不变随机过程法(Spherically Invariant Random Process)是目前最为常用的两种杂波模拟方法。本文对这两种方法分别作了简要介绍并详细论述了Weibull分布杂波的产生原理和基本流程。最后,利用ZMNL法对基于相干脉冲雷达杂波模型的相干Weibull分布杂波进行仿真。仿真结果与理论结果基本一致,证明此法是有效可靠的。
The zero memory nonlinearity transformation and the spherically invariant random process are two kinds of simulation methods for radar clutter used frequently at present. These two methods are introduced briefly and the principle and basic flow of Weibull distribution clutter are also discussed in detail. Finally, the coherent Weibull distribution clutter based on coherent pulsed radar clutter model is simulated by using ZMNL method. The simulated result is basically coordinated with that of the theory, and this method is proved to be effective and reliable.
