| 摘 要： | 首先介绍了联合战术信息分发系统(JTIDS)的一般概念,进而针对它的抗干扰措施———直接序列扩频的扩频码的优选及扩频图案的设计,提出了合适的算法,并用C语言在微机上仿真实现。实验结果证明优选的码字质量高,生成速度快,此方面的仿真实现逼近JTIDS,有利于对JTIDS进行深入研究,从而对它实施有效干扰。

| Abstract: | Firstly,the generic concept on Joint Tactical Information Distribution System(JTIDS) is introduced.Secondly,appropriate algorithm for antijamming is put forward,including the optimization of the direct sequence spread spectrum code and the design of the spread spectrum pattern.At last,all the algorithm are simulated on PC using language C.The results of the simulation represented that the optimized codes are in good quality and could be generated in fast speed.At the same time,the simulation results approach JTIDS at a high degree.It is valuable for further study and effective jamming on JTIDS. |
