Abstract
In order to overcome the calibration difficulty of error-correction parameters for ship-borne radar under dynamic condition, a new method based on star sensor is presented,in which angular measurement data obtained by means of star sensor is taken as comparison data. The present calibration methods for ship-borne radar are summarized,the principle of calculation method based on star sensor is introduced,and the error formula and the calculation model are derived. By calculating angle residual error of radar to star sensor and by using least square estimation method,the calculation of the error-correction parameters is re-alized. Finally, the method is verified by dock-static and wharf-dynamic experiments. The result shows in comparison with traditional calibration method, the consistency is within 15"under dock-static condition, and 25"under wharf-dynamic condition, which proves the feasibility of the method.关键词
