用于自适应天线的稳健的RLS算法

Robust RLS Algorithm for Adaptive Arrays

抗干扰通信是电子战的重要组成部分 ,自适应天线不仅具有很强的抗干扰能力而且可以与其它通信抗干扰技术相兼容 .自适应算法是自适应天线的核心 .本文把应用数学学科研究的热门方法之一“稳健估计 (RE)”应用于RLS算法中 ,得到稳健的RLS算法 (RRLS) ,理论分析与计算机模拟结果都证明了RRLS算法基本保持了RLS算法的优点 ,同时在抗突出值干扰方面 ,优于RLS算法 ,提高了RLS算法的稳健性 .

Anti-jamming communication plays an important role in electronic war.Adaptive arrays have very strong anti-jamming capability.The algorithm is the key of adaptive arrays.This paper applies the estimation method to RLS algorithm and RRLS is proposed.The theoretical analysis and simulation results show that the RRLS keeps the advantage of RLS and is superior to the latter in anti-jamming.
