Annotations languages:

The integral calculation method to determine the marine vessel azimuth coordinates by coastal watching radars is suggested. It takes into account the coordinate information from the maritime Automated Information System (AIS). Analytical dependence of the weighted average evaluations of the systematic azimuth errors due to inaccuracies in the azimuth rotation sensors mechanical installation of the Surveillance Radar Station (SRS) is determined. Experimental results of the coordinate information analysis obtained from the AIS and SRS are given. There was observed an approximately three-fold reduction in the integral error as compared to the results analysis of the coordinate information taken only from SRS.
