A Method for Enhancing the Ship-Sway Isolation Level in the Position Loop of Ship-Borne Radars

摘要

In this paper, a new method that can improve the ability of isolating ship sway in the manual model of the geodetic coordinate system is proposed. For the above method, the feedback gyro and feed forward gyro are introduced in the geodetic manual-mode of position loop. The theoretical analysis and experimental verification are conducted, and the results show that the ability of isolating ship-sway is significantly improved after the gyro loop being added which will greatly reduce the difficulty for the narrow beam ship-borne radar to capture target.
