摘　　要：MF-TDMA卫星通信系统中,网内终端本身具有频率跳变的能力,可以与跳频相结合实现抗干扰的目的。文章分析了MF-TDMA卫星通信和自适应跳频技术的特点,比较了两种常用的自适应跳频技术,并根据分析结果提出了一种基于分布式干扰检测、频点集中规划的自适应跳频MF-TDMA(AFH-MF-TDMA)卫星通信技术,该技术具有干扰检测准确、频率资源综合利用率高的特点,可以有效增强MF-TDMA卫星通信系统的抗干扰能力。In MF-TDMA satellite communication system, the termdnal has the capability of frequency hopping, and it is easy to improve the anti-jamming capability of system combining with frequency-hopping. The technical characteristics of MF-TDMA satellite communication and adaptive frequency hopping are analyzed and compared in this paper. Based on distributed interference detection and centralized frequency planning, an MF-TDMA adaptive frequency hopping （AFH-MF-TDMA） technique is put forward according to the analysis result. This technique can realize an accurate detection of interference and a more efficient allocation of frequencies. And it can effectively enhance anti-jamming performance of MF-TDMA satellite communication system.
