Error Analysis on GPS into Radar Coordinate Conversion

The conversion from GPS into radar polar coordinate is usually done in radar calibration.On the base of introducing the GPS accuracy and the model of GPS into radar polar coordinate,the effect of GPS error on the radar polar coordinate error has been studied in detail and the model has been given.Analysis on the effect of the changes of slant range,azimuth and pitch on the error of the coordinate conversion has been done under certain GPS error.The accuracy range of using ADS-B to calibrate radar is given under a certain precision in the GPS.
