Abstract
A system and technique for calibrating a plurality of radars provides a set of simultaneous equations derived from monostatic echo returns from a plurality of targets. A solution of the simultaneous equations provides relative position calibration factors and time delay calibration factors associated with the plurality of radars. The relative position calibration factors and the time delay calibration factors allow the plurality of radars to be coherently combined with only a small amount of processing gain loss compared with an ideal coherent processing gain.
