摘　　要：论文以如何提高卫星通信抗干扰能力为研究背景,通过对卫星通信技术发展现状的介绍,研究了卫星通信抗干扰体制问题,并提出技术上以扩谱技术为主,上行信号为扩谱信号,下行信号为TDM信号,信号的扩频过程由地面站来完成等符合现阶段要求的卫星通信干扰体制,该体制适合卫星通信特点、具有较强抗干扰能力,对卫星通信抗干扰体制研究有一定借鉴意义。This research background is how to improve the anti-jamming ability of satellite communication, Through the introduction of satellite communication technology development. The problem about the anti-jamming ability of satellite communieation＇s system is re searched, and spread spectrum technology on technical is proposed, and the uplink signal is spread spectrum signal, the downlink signal is TDM signal. The process of spread spectrum signal is from the ground station to complete to the requirements the antiamming ability of satellite communication＇s system of satellite communications at present. The system is appropriate for the characteristics of satellite communica tions, has more stronger anti-jamming＇s ability. It provides the reference meaning for the researching of anti jamming ability of satellite com- munication.
