Abstract：To solve the problem of limited transmission bandwidth during missile-borne flight,a power spectral density com-pression algorithm for telemetry vibration signals is designed to convert the transmitted telemetry vibration signals into transmitted power Spectral density(PSD)signals.By comparing the characteristics of different window functions,the truncation function which is most suitable for telemetry vibration signal is selected.In addition,the frequency domain averaging method is used to reduce the influence of random components on the spectral analysis results and to compress the data.Matlab simulation results show that Han-ning window can effectively suppress the sidelobe level weakening spectrum leakage phenomenon.The algorithm compresses the da-ta volume to 5%,which greatly improves the transmission efficiency of missile-borne flight.
