摘 要:基于虚拟仪器技术,提出了一种通用的模拟雷达信号发生系统,使用Python 语言设计控制程序控制AV1443 矢量信号源,利用MATLAB 仿真各类雷达信号得到相应的数据后,通过LAN 网络将信号写入AV1443 信号源中进行播放,实现雷达信号的产生,并通过一个具体示例展示该雷达信号发生系统的应用。该设计形式对于雷达信号模拟器模块化设计具有很好的借鉴意义。

Abstract:Based on the virtual instrument technology,a general analog radar signal generating system is proposed. The control program is designed with Python language to control the AV1443 vector signal source. After simulating various radar signals with MATLAB,the corresponding data is obtained,and the signal is written into the AV1443 signal source through LAN network for playback,so as to realize the generation of radar signal with a specific example shows the application of the radar signal generating system. This design form has a good reference for the modular design of radar signal simulator.
