摘要: 通信信号的个体识别是近年来通信侦察领域的一个重要研究课题,也是一个比较复杂而困难的问题.目前针对相同型号、相同工作模式的通信信号的个体细微特征的提取、分析和识别方法多处于一个初步研究阶段.提出了一种细微特征提取方法,并利用特征参数集实现了多个电台的个体识别.实验结果表明该方案识别率较高,具有较强的实用性和可行性.

Abstract: Individual communication signals identification is an important issue in the field of communication reconnaissance in recent years.It is also a difficult and complex problem.Aiming at the different transmitters of the same type and working mode,the methods for the fine feature extraction,analysis and recognition are at the preliminary study.A method of fine feature extraction is proposed,and the identification of several transmitters is achieved by the statistic properties of the feature parameters set.Finally,the experiment results show that this method is feasible and practical,and has a high recognition rate.
