摘　　要：首先介绍了通用数据链(CDL)的技术特点,对CDL的干扰策略进行了讨论,分析了几种干扰样式的可行性。研究了脉冲干扰对CDL前向链路的BPSK扩频调制的干扰效能,对脉冲干扰下BPSK扩频调制的误码率及同步字差错率进行了计算。研究了宽带噪声干扰对CDL返向链路的OQPSK调制的干扰效能,对宽带噪声干扰下OQPSK调制的误码率进行了计算,最后分别进行了仿真分析。仿真结果显示,所研究的干扰样式在一定条件下对CDL通信链路能产生有效的干扰。Originated from the technical characteristics of CDL（Common Data Link）,the jamming strategy for CDL is analyzed,the feasibility of various jamming forms is researched. The jamming effectiveness of pulse jamming to BPSK spread spectrum systems and BBN jamming to OQPSK are analyzed and simulated. The BER and synchronization word error rate of pulse jamming to BPSK spread spectrum systems are calculated,and the BER of BBN jamming to OQPSK is calculated. The simulation results show that the jamming mode researched have the ability to interfere CDL communication link in some situation.
