建立了一套基于VISA和Mint的微波暗室自动测量系统,通过计算机控制矢网和转台以实现高效率的天线与RCS的微波暗室自动测量。在Visual C++开发环境下,运用多线程技术将矢网和转台结合,同时采用VISA和SCPI命令实现矢网的自动控制,采用Mint ActiveX控件技术实现转台的自动控制,该方法易于实现矢网与转台的高效同步。实测表明,该系统操作方便,测量效率、测量精度与自动化程度较高,所采用的控制方法有着较好的通用性和可拓展性,具有广阔的应用前景。

In order to realize efficient automatic antenna and RCS measurement, a microwave anechoic chamber automatic measurement system has been established, using the computer to control the vector network analyzer and the test turntable. In visual C++ development environment, the multithread technology is used to combine the vector network analyzer with the test turntable. The vector network analyzer is auto-controlled by VISA and SCPI command; the test turntable is auto-controlled by Mint ActiveX control technology. The methods are easy to efficiently synchronize the two devices. The actual measurement shows that the system is easy to control, and has high measurement efficiency, high precision, and high automaticity. The controlling method has broad application prospects for it has good universality and is easy to expand.
