摘　　要：为了方便实现对任意信号的时频分析与仿真,运用信号的短时傅里叶变换,基于.NET组件技术,采用VB.NET和Matlab混合编程,设计开发一种可独立运行的信号时频分析仿真软件.通过在Matlab软件中建立信号模型,自定义设置时间间隔,对信号分段进行频域分析和时域分析,使抽象复杂的信号时频分析很容易实现;采用VB.NET制作人机界面,调用Matlab制作的.NET组件,较好地解决了软件运行效率和界面友好的问题,制作成安装软件包,运行实例证明该仿真软件可以为学员学习信号课程提供较好的辅助工具.For the sake of time-frequency analysis of any signals and their simulation, this paper designs a simulation software for signal＇s time-frequency analysis that can be operated independently, by using the signal＇s short time Fourier Transform and hybrid programming of VB.NET and Matlab based on .NET component. By setting up the signal model in Matlab software, custom setting the time interval, the time and frequency domain analysis of signals is implemented in segment, making the time-frequency analysis of complex signals easy. The human-machine interface produced by using VB.NET and .NET component made by using Matlab can be used well for software operating efficiency and user friendly. By operating the installation software package generated, it is shown that the simulation software can be used as the better aided tool for students learning the signal course.
