The Use of GPS in Radar Calibration

James V. Melody and Peter Kramarenko

Abstract:	A method has been proposed to check radar accuracy while at sea. The technique is to use the GPS receiver on the platform and the GPS receiver on the target to accu- rately locate both the platform and target. Knowing the location of the platform and the target, the direction and distance from the platform to the target are measured with the radar. With GPS as the standard, the accuracy of the radar can be determined. There are of course some con- cerns with such a scheme which this paper will address. These include how to collect and compare the data from both the GPA receivers and the radar. The expected radar calibration accuracy that can be achieved in the normal mode as well as differential mode will be stated. Also, the accuracy improvement when the platform and target are using the same satellite set will be discussed, With these estimated accuracies and the known measurement accu- racy of the radars, the exact requirements for each radar to be calibrated can be determined. At the current time the U.S. Navy has this process under consideration for calibration and checking of accuracy of shipboard radars.
