Abstract
A phased array frequency-modulated continuous-wave (FMCW) radar configured to operate to transmit, using at least one antenna, a calibration signal, to receive, using the antenna, a reflection of the at least one calibration signal from a calibration target, to determine, based on the at least one calibration signal, a phase shift factor, to estimate, based on the phase shift factor, a transmitter trace distance and a receiver trace distance, to transmit, using the antenna, at least one target signal, to receive, using the antenna, a reflection of the at least one target signal from a target, and to determine, based on the at least one target signal and the transmitter trace distance and the receiver trace distance, a range of the target.
