虚拟仪器技术在众多领域得到了广泛的应用。文中针对雷达自动测试系统中对虚拟仪器的需求，分析了目前流行的虚拟仪器编程软件Labwindows／CVI在数值分析和信号处理方面的不足之处，提出了一种在Labwindows／CVI环境下利用ActiveX技术调用MATLAB工具箱中的函数，从而实现混合编程构建虚拟仪器的简单易行的方法，并用该方法实现了雷达信号分析虚拟仪器的设计。

The technique of virtual instrument has been applied widely in many fields. In this paper, according to the request for a virtual instrument in radar automatic test system,the disadvantages of popular programming software for virtual instrument like Labwindows/CVI in numerical analysis and signal processing have been analysed first. Then a simple and easy technique of constructing virtual instrument was presented under the environment of Labwindows/CVI calling the functions in MATLAB toolbox with ActiveX technology,and an example of radar signal analysis virtual instrument was given to illustrate the process of realization.
