Abstract
A frequency modulated continuous wave (FMCW) radar system that includes a transceiver coupled to an analog to digital converter (ADC), and a digital signal processor (DSP) coupled to the ADC. The transceiver is configured to transmit a plurality of FMCW chirps, receive a plurality of reflected FMCW chirps, and mix the plurality of reflected FMCW chirps with at least one of the FMCW chirps to generate a plurality of beat signals. The reflected FMCW chirps are the FMCW chirps after being reflected off of a target object. The ADC is configured to convert the beat signals into a plurality of digital chirps. The DSP is configured to receive the digital chirps and quantify a plurality of vibration parameters for the target object based on a comparison of phase information in a frequency domain between one of the plurality of FMCW chirps and one of the plurality of digital chirps.
