关于电子通信系统复合式干扰的智能识别研究

Research on Intelligent Identification of Compound Interference in Electronic Communication System

鉴于一般方法对电子通信系统复合式干扰识别精准度不高的现状,提出一种针对性的智能辨识技术。首先对电子通信系统中速度与距离联合欺骗干扰的运作流程展开数学剖析,给出基于拖引头坐标系滤波的信号跟踪模型,使复合干扰信号能够被初步检测。其次借助常规时域特征萃取手段,对复合干扰信号作进一步识别,但区分精细度不够。再次通过规则库添加和识别流程分支化,使每一子流程均有对应的特征和规则库,以此直接辨识复合式干扰信号。最后进行实证检验,检验结果表明所提方法效率较高,且在稳定性与鲁棒性层面也有良好表现。

In view of the current situation that the general methods are not accurate in the identification of composite interference in electronic communication systems,a targeted intelligent identification technology is proposed.Firstly,the operation flow of velocity and distance combined deception jamming in electronic communication system is analyzed mathematically,and the signal tracking model based on the filtering of the seeker coordinate system is given,so that the composite jamming signal can be detected preliminarily.Secondly,with the help of conventional time-domain feature extraction methods,the composite interference signals are further identified,but the discrimination precision is not enough.Thirdly,add and identify process branching through rule base,so that each sub process has corresponding features and rule base,so as to directly identify composite interference signals.The last is empirical test.The results show that the proposed method is efficient and performs well in stability and robustness.
