摘　　要：提出了直接序列扩频和自适应调零天线相结合的卫星通信抗干扰设计思路,针对不同干扰条件和不同卫星转发方式,进行了系统抗干扰性能的理论分析,结果表明,直接序列扩频和自适应调零天线相结合,经星上再生处理转发可有效提高系统抗干扰能力。相关分析与结论对工程应用具有一定的参考意义。A satellite communication anti -jamming design combing direct sequence spread spectrum（DSSS） and adaptive nulling antenna is proposed. For different jamming conditions and satellite transponding modes, theo- retical analysis of system anti - jamming performance is given. It is concluded that the system anti - jamming ca- pability can be effectivly improved by combining DSSS and adaptive nulling antenna and then performing onboard regeneration processing and transpending.
