摘　　要：针对当前卫星通信载波监视频谱数据分析挖掘不够深入、不能快速提取数据本身蕴含的潜在信息,达到快速排查、识别干扰源的问题,提出基于频谱监视的卫星通信特定终端识别方案,通过采用改进型基于内插的前向结构码元定时同步法、相干解调法中的信号载波同步法等对IQ数据进行解调分析,设计独特字提取方法,获得信号载波独特字信息,并利用独特字的自相关特性,达到快速识别信号特定终端的目的。In view of the problem that the analysis and mining of the current satellite communication carrier surveillance spectrum data is not deep enough to quickly extract the potential information contained in the data itself in order to achieve the rapid troubleshooting and identification of interference sources,a satellite communication specific terminal identification scheme based on spectrum surveillance is proposed.The IQ data are demodulated and analyzed by adopting an improved forward structure code timing synchronization method based on interpolation,as well as a signal carrier synchronization method in the coherent demodulation method.Then a unique word extraction method is designed to obtain the unique word information of the signal carrier,and the autocorrelation characteristics of the unique word can be used to quickly identify the specific terminal of the signal.
