Solution of the problem of identification of systematic errors of several radars in azimuth with multidimensional optimization algorithm

The problem of finding the systematic errors in azimuth of several radars by observing an aircraft motion on some time interval is considered. Input data from each radar are sets of measurements of the slant range and azimuth. The spatial trajectory of an aircraft is additionally reconstructed during calculation of the radar error in azimuth. The elaborated algorithms are tested on simulated and real data. Moreover, an option of algorithms is considered when the systematic error depends on the direction from the radar to the aircraft.
