Abstract: The dynamic change of firing zone under ship swaying and its effect on the weapon-target assignment (WTA) are studied. A target moving model in the deck reference system is built, and a ship swaying error angle (SSEA) model is proposed, which can illustrate the relationship between the target position and the firing zone under swaying. The rules of WTA under swaying are drawn with the SSEA as an evaluation index. The maximum SSEAs in four sway modes are computed via simulations. The results show that the maximum SSEA can be used as a valid basis for WTA under the ship swaying and provides a reference for designing the firing overlap zone.
