The purpose of this study is to provide a fast, continuous and accurate alternative positioning method for coastal ships under the condition of abnormal satellite positioning; On the basis of the traditional artificial radar location, a position information based on the reference target is developed, the target tracking function of radar is applied, the distance and azimuth data of the reference target to the ship are automatically collected, and the automatic radar location method of the ship's position is determined by means of the mathematical model of track; Through the experimental calculation and the real ship data, it is proved that the radar location with high precision can be realized under the condition that the reference target position information is obtained accurately.
