Claim 0:
1. A radar system configured to calibrate for system impairments, wherein the radar system comprises:
a transmitter configured to transmit radio signals;
a receiver configured to receive radio signals that include radio signals transmitted by the transmitter and reflected from objects in an environment, wherein the transmitter and the receiver are coupled to an antenna array;
a calibration module comprising a platform configured to rotate the receiver and the transmitter in both azimuth and elevation, wherein an array center of the antenna array is not aligned with the platform's rotation center;
wherein, in the presence of at least one object, the calibration module is operable to collect from the receiver reflected signals from the at least one object at desired angles of interest in azimuth and elevation, wherein the calibration module is operable to calculate a misalignment value for a misalignment between the array center of the antenna array and the rotation center of the platform, and wherein the receiver is operable to correct for phase distortion and angle-of-arrival error due to the misalignment based upon the calculated misalignment value.
