摘要

摘要: 为了有效消除鱼雷电磁引信收发天线之间的直接耦合干扰, 弥补传统方法的不足, 提出了一种基于自适应递归最小二乘( RLS)算法的干扰消除新方法。首先分析了自适应滤波器的一般原理; 其次阐述了RLS算法的滤波原理和实现流程; 最后结合典型的鱼雷电磁引信过靶参数并设置不同的耦合干扰强度, 在MATLAB 环境中进行了算法的仿真研究。仿真结果表明, 采用该方法可在直接耦合干扰的幅值是目标信号幅值的10万倍的条件下将其有效消除, 是一种消除同频强背景干扰的有效方法。此外, 该方法还具有自适应算法运算量小、收敛速度快和实时性数据处理等优点。

Abstract: In order to effectively reduce the direct coupling interference between the transmitting antenna and receiving antenna in torpedo electromagnetic fuze, and overcome the shortcomings of the conventional methods, a new interference elimination method is put forward based on the adaptive recursive least square (RLS) algorithm. The general principle of adaptive filter is firstly analyzed, and the filtering principle and implementation flow chart of the adaptive RLS algorithm are discussed. Simulation analysis of the algorithm is carried out in MATLAB environment by considering the representative hitting parameters of torpedo electromagnetic fuze and setting different intensity of direct coupling interference. Simulation results show that by using the present interference elimination method, the direct coupling interference can be eliminated in the condition where the amplitude of the direct coupling interference is 100 000 times of the target signal’s amplitude. In addition, the method has such advantages as low calculation amount, rapid convergence and real-time data processing
