  • Circuits and methods for determining chirp signal linearity and phase noise of a FMCW radar
    Patent number: 10746851
    Abstract: A testing device for FMCW radar includes an input for receiving a chirp signal generated by the radar. An IQ down-converter coupled to the input down-converts the chirp signal. A digitizer extracts digitized IQ signals from the down-converted chirp signal. A processor coupled to the digitizer determines at least one of frequency linearity and phase noise of the chirp signal.
    Type: Grant
