摘　　要：在我国现阶段的卫星通信系统中,多频时分多址技术是一种比较流行的技术,其具备相对完善的跳频能力,也能够以此为基础,实现较好的抗干扰效果。文章主要以多频时分多址技术为研究基点,分析当前的自适应跳频技术,并研究在卫星通信过程中,对相关干扰的检测,最后论述自适应跳频对干扰的躲避应用。In this stage of China＇s satellite communication system,the multi-frequency time division multiple access technology is a more popular technology,which has relatively sound frequency hopping capability, on this basis,can achieve better anti-interference effect. Mainly taking multi-frequency time division multiple access technique for the study of basis points,Immunity the paper analyzes the current adaptive frequency hopping technology, and researches detection of the relevant interference, in satellite communicationand finally discusses the application of adaptive frequency hopping to avoid interference.
