Abstract
A system and associated method for calibrating a radar system is described, wherein the radar system includes a phased array antenna including a first antenna array and a second antenna array, a transmitter array, and a receiver array, communication leads, a calibration circuit, and a controller. The calibration circuit includes a power divider and directional couplers. A pilot signal is injected, via the power divider and the directional couplers, to the receivers during a quiet period. Phase offsets and gain imbalances for the receivers are determined in relation to a reference channel based upon the pilot signal, and phase calibrations and gain calibrations for the receivers are determined based upon the phase offsets and the gain imbalances, and a radar-related parameter is based upon the phase calibrations and the gain calibrations for the receivers.
