相关随机序列仿真的一种新方法

相关随机序列是描述随机噪声、杂波和干扰的主要工具,在卫星通信、常规雷达及星载雷达中有着重要应用.本文基于“随机向量抽样法“,提出了一种新的相关随机序列仿真方法.这种方法通过由相关函数抽样序列形成的协方差矩阵控制序列的相关性,适用于仿真具有不同概率密度函数的各种有限长相关的随机序列.仿真结果表明该方法可快速、准确地实现各种相关随机序列的仿真.

A New Method for Correlated Random Series Simulation

Correlated random series is the mainly tool for describing the property of random noise,clutter and jamming,which is widely used in satellite communications,normal radar and spaceborne radar.Based on "Random vector drawing",a new method is proposed for correlated random series simulation in this paper.This method can control the series correlation via covariance matrix that was formed from correlation series and is suit for simulating finite correlated random series of different distributions.The simulation results show that the method can simulate many kinds of correlated random series accurately and quickly.
