Abstract

A signal processing method for a frequency-modulated continuous waveform (FMCW) radar system includes receiving a plurality of feedback signals from a plurality of targets and performing analog to digital conversion on the plurality of feedback signals to obtain a digital receiving signal corresponding to the plurality of feedback signals, performing a window function on the digital receiving signal to obtain a window transformation signal corresponding to the digital receiving signal, performing time-domain to frequency-domain conversion on the window transformation signal to obtain a spectrum signal of the window transformation signal, performing two beat frequency detections on the spectrum signal, and determining distances and speeds of the plurality of targets in comparison to the FMCW radar system according to results of the two beat frequency detections.
