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 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 relative velocity of the target object as compared to a velocity of the FMCW radar system by removing an effect of a range to the target object from a two dimensional range Doppler processing signal.
