摘　　要：针对卫星导航系统干扰模拟与抗干扰测试需求,基于半实物仿真原理,提出了一种利用ADS软件和矢量信号发生器产生自定义波形复杂信号的方法。对半实物仿真系统的硬件平台的搭建要点进行了介绍,完成了复杂信号在ADS系统平台下的建模与仿真,阐述了半实物仿真流程。利用矢量信号分析仪89600S对生成的复杂信号进行了测试,并通过与ADS仿真结果的对比分析,验证该方法的可行性。In order to meet the demands of interference simulation and anti-jamming test of satellite navigation system, this paper presents a method for generating complex signals whose waveforms is user-defined with the simulation software ADS and the vector signal generator based on semi-physical simulation, and makes brief introduction on the key points of establishing the hardware platform of the semi-physical simulation. The modeling and simulation of complex signals are completed upon the ADS system platform and the working flow of the semi-physical simulation is described. Finally, the generated complex signals are tested by using the vector signal analyzer 89600S. Moreover,through comparisons and analysis,the feasibility of the proposed method is validated.
