摘要
提出了基于GUI和矢量信号源的微波着陆信号模拟器设计方法。首先利用MATLAB图形用户界面开发环境设计了集信号参数设置、干扰模拟和基带数据生成于一体的基带波形仿真功能;其次提出了一种改进的扫描波束模拟方法,实现了对微波着陆扫描信号的精确模拟;最后利用矢量信号源MG3700A对基带数据进行混合调制。测试结果表明,该信号模拟器达到设计要求。
A design method of microwave landing signal simulator based on GUI and vector signal generator is proposed in this paper. First,a human-computer interaction interface with the function of signal parameters setting,interference simulation and baseband data generation is designed by MATLAB GUIDE. Second,an improved method of the scanning beam simulation which can realize accurate simulation of the microwave landing scanning single is proposed. Finally,baseband data is hybrid modulated by using vector signal generator MG3700 A. The test results show that the signal simulator meets requirements of design.
