Abstract：To solve the problem of UAV flight safety,a spectrum analysis system of UAV vibration information based on DSP is proposed,which collects and analyzes the UAV vibration signal in real time,records the vibration signal and analyzes its frequen-cy domain information,including the amplitude and phase of each frequency.It provides a variety of data interfaces,which can not only analyze the vibration spectrum characteristics in real time and upload the airborne link,but also provide data support for re-al-time monitoring of UAV flight status.It can also download and store the data afterwards to provide a practical basis for analyzing and evaluating the flight status of the UAV during the whole period.At the same time,the system uses four 5-order Nuttall window FFT algorithms to solve the spectrum leakage problem in vibration signal spectrum analysis,ensure the accuracy of the data,and greatly improve the reliability of the system.
