Abstract
An object recognition method includes generating Doppler spectrogram data according to an echo signal, the echo signal being relating to an object; transforming N sets of time-domain data of the Doppler spectrogram data corresponding to N velocities into N sets of cadence spectrogram data, respectively; combining the N sets of spectrogram data to obtain 1D/2D cadence spectrum data, and acquiring a series of cadence feature from the 1D/2D cadence spectrum data to recognize the object.
