摘　　要：卫星通信系统仿真平台可以完整模拟卫星通信链路,并能有效分析卫星通信系统的抗干扰能力,从而达到减少外场试验次数,加快研发周期,节约硬件资源的目的。选用安捷伦公司开发的ADS(advanced design system)软件建立该仿真平台。通过对ADS现有模块的二次开发,搭建了直序扩频(DSSS)信号发生调制模块、发射机模块、接收机模块等,开发了新的ADS干扰信号发生模块和同步互相关模块,进行了正常通信下和单音干扰下卫星通信链路的模拟仿真。The satellite communication interference suppression system simulation platform can simulate the whole satellite links and effectively analyze the performances of satellite communication system interfered by single tone, which reduces the cost of experiments, shortens the development cycle and saves the hardware resource. Based on ADS software, a satellite communication interference suppression system simulation platform is constructed. The advanced DSSS signal producing and modulating model, transmitter model, receiver model and other models are set up on basis of the provided basic ADS models. The new ADS interference producing model and cross relation model are developed. The whole satellite links based on ADS soft ware with the single tone interference has been simulated.
