Abstract The present disclosure provides a signal processing method and device. The method comprises: processing a radar echo signal to obtain a thoracic cavity movement signal, wherein the radar echo signal is an echo signal generated by a target object reflecting an electromagnetic wave emitted from a radar; filtering the thoracic cavity movement signal by using a filter to obtain a respiratory signal and a heartbeat signal, wherein the respiratory signal corresponds to a respiratory bandpass frequency of the filter, and the heartbeat signal corresponds to a heartbeat bandpass frequency of the filter; and performing joint time-frequency domain processing on the respiratory signal to obtain a respiratory frequency corresponding to the respiratory signal, and performing joint time-frequency domain processing and data statistical analysis on the heartbeat signal to obtain a heartbeat frequency corresponding to the heartbeat signal. The present disclosure solves the technical problem in the related art that in radar-bas
