摘要
为了探讨舰载近程武器系统(CIWS)对小航路捷径(SFC)超音速反舰导弹(SM)的拦截能力,研究分析了SM末端三维广义比例导引攻击特性,通过构建CIWS随动系统的PID控制模型,在CIWS与SM的动态对抗中实时解算射击误差.提出了一种速度等效法迭代求解射击前置角,结合CIWS弹丸衰减规律和射击边界条件,建立了CIWS对空射击模型.在建立三维SM受弹模型的基础上,探讨了不同SFC下SM的突防能力,给出了SM在中弹数量以及毁伤部位等方面的详细信息.结果表明,与亚音速导弹相比,SM在不同SFC下的总受弹数量较低.对于SM,平均有54.9%的受弹部位处于弹体尾部的非致命区,对于亚音速导弹,非致命区部位的受弹比例只有27.1%,导致SM对CIWS保持较高的突防能力.论文研究内容可以为探讨CIWS的作战应用以及验证靶场实验结果的置信度提供参考.
In order to verify the interception ability of a ship-borne close-in weapon system （CIWS） to a supersonic anti-ship missile on a shortcut flight course （SFC）, the 3D generalized proportional navigation attacking ballistic characteristics of supersonic missile （SM） were analyzed, by establishing the proportion integration differentiation （PID） control model of CIWS servo system, a dynamic tracking error of the servo system was also calculated in real time during the course of interception and a velocity equivalent method was utilized to compute CIWS shooting an- gles iteratively. By combining the projectile velocity attenuation equation and shooting boundary condition of CIWS, an air defense model of CIWS was established. Under a 3D body model of SM, penetration ability of SM on differ- ent SFCs was studied extensively and further information of the hit counts and damage locations of SM are available. The simulation result indicates that, compared with subsonic missiles, the total hit counts （THC） of CIWS to SM dropped to a certain degree, and 54.9% of THC located on the nonfatal parts of SM, whereas, the subsonic missile had only 27.8% THC located on the nonfatal parts, which lead to higher penetration probability of SM to CIWS. The research study results provide significant reference to the operational application of CIWS and the confidence of shooting range experimental theory
