Automated Vehicle Radar System With Self-Calibration

An automated vehicle radar system (10) capable of self-calibration includes an antenna (22), a transceiver (32), and a controller (40). The antenna (22) broadcasts a radar-signal (28) and detects a reflected-signal (30) reflected by an object (20). The transceiver (32) determines a distance (34), an angle (36), and a range-rate (38) of the object (20) relative to the antenna (22) based on the radar-signal (28) and the reflected-signal (30). The controller (40) determines a speed (44) of a host-vehicle (12); determines when the object (20) is stationary based on the speed (44), the angle (36),and the range-rate (38); stores in a memory (42) a plurality of detections (48) that correspond to multiple instances of the distance (34), the angle (36), and the range-rate (38) as the host-vehicle(12) travels by the object (20); selects an ideal-response (52) of angle (36) versus range-rate (38) based on the speed (44); determines a calibration-matrix (54) of the system (10) based on a difference between the plurality
