Claim 17:
18. A calibration system, comprising at least one processor configured to:
cause a flat plate target to be at a first position in a test environment, the first position being relative to a mounting position of a particular radar sensor of a radar system that is arranged in the test environment to be calibrated, and including a respective elevation angle and a respective translational position relative to the mounting position of the particular radar sensor;
collect, from the particular radar sensor, first data indicative of first radar signals that reflect off of the flat plate target at the first position;
determine, based on the first data, a first calibration error for the particular radar sensor at the first position;
cause the flat plate target to be at one or more additional positions relative to the mounting position of the particular radar sensor, each of the additional positions including a respective elevation angle and a respective translational position relative the mounting position of the particular radar sensor;
collect, from the particular radar sensor, additional data associated with each of the additional positions, the additional data being indicative of additional radar signals that reflect off of the flat plate target at each of the additional positions;
determine, based on the additional data associated with each of the additional positions, an additional calibration error for each of the additional positions;
determine, based on the first calibration error for the first position and each additional calibration error for each of the additional positions, a combined calibration error for that particular sensor given the mounting position of the particular radar sensor within the radar system; and
output an indication of the combined calibration error for use in compensating the radar system for the combined calibration error of the particular radar sensor to calibrate the radar system.
