Based on differential global position system (GPS) technology, a general calibration method of shipboard radar is established. The basic principle of this method is introduced and the transformation model of coordinate and calculating equations are provided. Then the ways to ensure data matching and dispose the system errors are discussed, some problems that may occur during the calibration process are analyzed, and finally, the normative calibration theory is formed. The study indicates that the calibration method using differential GPS technology has a good applicability, can be used to calibrate shipboard radar in different working cases and provide a technical base for investigating new calibration method.
