摘　　要：Dear editor,The micro-Doppler modulation caused by the rotors on an unmanned aerial vehicle(TJAV)can be employed to recognize the UAV.However,several rotors on a UAV,as well as multiple targets at the same scene,lead to a multicomponent micro-Doppler signal in the radar echo.Conventional signal decomposition is an important method for extraction of the features from micro-Doppler signals [1].although it is incapable of separating characteristic curves that are overlapping [2] in the lime-frequency(TF)plane in the ease of multicomponent,micro-motion,which can lead to the poor precision of parameter estimation.
