Study on the method of ship swaying isolation in the ship’s radar digital guidance manner

Through the analysis of the traditional digital guidance manner of the ship-borne X-band measurement and control system and the comparison with the geodetic angle digital guidance manner of the improved feedback gyroscope, the working principle and the realization process are analyzed in detail. In order to verify that the modified digital guidance manner can improve the ship swaying isolation, the ship swaying isolation of the new digital guidance manner is tested and the data are collected by using the method of tracking geostationary orbit satellites and ship rolling test. By analyzing the angle data of ship rolling, it is found that the ship swaying isolation of the new digital guidance manner is increased by about 14 dB compared with the traditional digital guidance manner, which achieves the goal of reducing the influence of ship shake on the measurement. At the same time, the equipment performance of X-band measurement and control system has been further grasped.
