An example radar device includes an antenna system, a transmitter having an input, and an output coupled to an input of the antenna system, the transmitter having modulation circuitry to provide frequency modulated continuous wave (FMCW) signals for transmission by the antenna system; a receive signal processing chain; and a digital front-end. The receive signal processing chain includes an input coupled to an output of the antenna system, and is configured to receive radar reflection signals, process the radar reflected signals to generate an intermediate frequency (IF) baseband signal, and digitize the IF baseband signal to generate digital samples of the IF baseband signal. The digital front-end has an input to receive the digital samples of the IF baseband signal and to phase-shift the digital samples in response to a calibration signal.
