互调干扰信号的特征识别

Intermodulation Distortion Character Identify

在复杂电磁信号环境中,实际存在为数不少的互调干扰信号,对这类信号的有效分析识别,是无线电监测工作需要重点关注解决的难题。对互调干扰信号在幅度特征和频谱峰值特征两个方面的特性进行了分析,给出了互调干扰信号识别的思路。

This paper makes a brief introduce of how to identify intermodulatio distortion in a complex signal environment, especially, from two points of the singal's characters , amplitude and frequency , which is difficult problem during the detection process. At the end of the paper, discusses the application of the technology in detection analysis systems, and gives its flow chart.
