信号指纹识别技术发展与应用

Development and application of signal fingerprint identification technology

由于制造工艺的细微差别,通信辐射源内部电路存在硬件差异,其发射信号会体现出区别于其他辐射源个体的特征,即为信号指纹。利用信号指纹识别技术,可以识别同型号的不同辐射源个体,进行信号追踪、监测,实现军事打击。论述了信号指纹识别技术的原理,分析了国内外关于信号指纹提取与识别的研究现状,展望了该技术未来在军事和民用领域的应用。

Due to the subtle differences in manufacturing processes,there are hardware differences in the internal circuits of communication radiation sources,and their transmitted signals will reflect the characteristics different from other radiation source individuals,that is,signal fingerprints.By using the signal fingerprint identification technology,different radiation source individuals of the same model can be identified for signal tracking and monitoring to achieve military strike.This paper discusses the principle of signal fingerprint identification technology,analyzes the research status of signal fingerprint extraction and identification at home and abroad,and prospects the application of this technology in military and civil fields in the future.
