Aiming Point Correction Technique for Ship-launched Anti-air Missiles Considering Ship Weaving Motion

In order to intercept anti-ship missiles, it is important to accurately predict the aiming point.The major factor for degrading the accuracy of the aiming point is the motions of the warships due to waves.Therefore, a stage of correcting the aiming point is required to compensate for such motions of warships.The proposed aiming point correction technique treats the changes in positions and velocity of naval guns by considering changes in the positions and velocities of the anti-ship missiles.In this paper, a ship motion estimation filter was also constructed to predict the motions of warships at the firing time of naval guns.In the simulation part, finally, the distance errors before and after aiming point corrections were compared through 6-DOF simulations.
