As a popular signal of radar,the linear frequency modulation(LFM) signal can increase the detection range with larger average emitted power. In order to improve study intrest and condition of the students,a virtual experiment platform for analyzing the LFM signal was designed with hybrid programming technology of LabVIEW and Matlab. The platform includes LFM signal analysis platform and pulse compression simulation platform,and has convenient operability. As a result,the stu?dents can understand the feature and the principle of time?frequency domain with deep impression. The application method of the platform in teaching is proposed.
