Aiming accuracy improvement of a warship cannon in consideration of ocean environments

초록

In order to intercept an anti-ship missile by a warship cannon, the accurate prediction of an aiming point is very important. The two error sources degrading the aiming accuracy are target's future acceleration and the ship's motion due to ocean wave. The basic idea of the proposed method is that changing position and velocity of the cannon due to ship's motion is considered as the offset of anti-ship missile's position and velocity. In this way, the firing table of the cannon to determine the aiming point of the cannon in stationary state can be directly used without any calibration. © 2012 SICE.
