Abstract
A radar system and method for calibrating a radar system, the method including the steps of: measuring a set of azimuth angles of the radar system to obtain a plurality of measured azimuth array responses, wherein the radar system is physically rotated about a first axis of the radar system between each azimuth angle measurement; measuring a set of elevation angles of the radar system to obtain a plurality of measured elevation array responses, wherein the radar system is physically rotated about a second axis of the radar system between each elevation angle measurement; obtaining an azimuth calibration matrix based on the plurality of measured azimuth array responses and an elevation calibration matrix based on the plurality of measured elevation array responses; and configuring the radar system to apply the azimuth calibration matrix and the elevation calibration matrix to one or more antenna array responses.
