电台指纹识别技术研究综述

Survey of Radio Station Fingerprint Identification Technology

由于各个通信电台在硬件制造工艺上的细微差异,导致电台发射的信号频谱上携带区别于其他电台的个体特征,即电台指纹。电台指纹识别在当今通信对抗领域中电台个体的识别、侦查、监测、定向打击等军事活动中扮演着越来越重要的角色。从电台指纹产生机理分析入手,整理和归纳能够作为电台个体识别依据的指纹特征相关的研究理论和成果,总结常用实现同一型号、不同电台个体识别的特征参数提取方法,并且对电台指纹识别技术在军事和民用方面的应用前景作出展望。

Due to the slight differences in the hardware manufacturing process of each communication station,the signal spectrum transmitted by the station carries an individual characteristic that is different from other stations,namely the station fingerprint.Radio fingerprint recognition plays an increasingly important role in military activities,such as identification,reconnaissance,monitoring,and targeted strikes in the field of communication confrontation.Starting from the analysis of the radio station fingerprint generation mechanism,the research theories and results related to the fingerprint characteristics that can be used as the basis for individual radio station identification are organized,and the feature parameter extraction methods commonly-used to achieve the same model and different radio station individual identification summarized,and finally the application prospects of radio fingerprint identification technology in military and civilian applications forecasted.
