摘　　要：扩频测控系统抗不同形式干扰的性能有较大差异,就此进行了重点研究。通过理论分析和仿真比较了扩频系统对多种干扰信号的抗干扰机理和抗干扰容限,并给出了具有抗干扰能力的扩频接收机的设计思路与建议。研究结果可为扩频系统的设计和抗干扰试验提供参考。The anti-jamming performance of direct sequence spread spectrum（DSSS） TF＆C system is different under different interferences. The differences are discussed. The anti-jamming principle and capacity of TT＆C systems under different interferences is compared through theoretical analysis and simulation, and on this base, the suggestion of designing a spread spectrum TT＆C receiver with anti-jamming ability is given. The study result provids reference for spread spectrum rIT＆C system design and anti-jamming testing.
