Keywords: geometric matching, aircraft tracks, systematic errors of radars
A problem of processing the measurements from air surveillance radars is considered. The measurements are provided by observation of air traffic. This processing aims at matching the tracks of aircrafts obtained by various radars and estimation of their systematic errors. The error estimates are built in the form of a "collection of corrections" for radars measurements. For finding estimates, redundancy of observations with data from several radars is used. In the approach suggested, neither one of radars is regarded as the reference standard in principle. The systematic errors are defined by combined procession of measurements from "neighboring" radars with overlapping observation zones.
