摘要
ADS软件广泛应用于数字基带、射频和通信系统仿真,具有高效、便捷和协同仿真能力强的特点。介绍了典型的卫星通信系统和通信过程,并将ADS软件应用于复杂电磁环境模拟、卫星通信系统和地面对抗终端构建以及干扰效果评估。通过对仿真工具、测试工具和数据统计分析工具的使用,得出干扰信号调制样式、干信比和干扰信号码速率等因素对干扰效果的影响,并提出了部分优化干扰系统,提升干扰效果的建议。
ADS software is widely used in digital baseband,RF and communication systems simulation,with such characteristics as high efficiency, convenience and powerful co-simulation capability. This paper introduces the typical satellite communication system and communication process, and uses ADS software in simulation of complex electromagnetic environment, satellite communication sys- tems and ground electronic countermeasures terminal establishment as well as jamming effects assessment. The influence of such factors as modulation model ,jamming-signal ratio and transmission bit rate of jamming signal on jamming effect is obtained by using simulation tool, test tool and data statistic and analysis tool. The suggestion of partial optimization of jamming system is put forward to enhance the jamming effect.
