为了提高非标准条件下舰载火炮射击命中精度,根据火炮弹道方程,建立实际条件下的火炮弹道仿真模型,分析研究舰船运动和海区气象等参数误差与火炮射击命中精度的关系。仿真结果表明,对于某型火炮,0.5°的航姿误差造成弹着点误差超过80 m;1 m/s的风速误差造成弹着点误差超过30 m;1%的气压误差引起弹着点误差超过20 m。因此,实际条件下火炮射击时,为了提高首发命中精度,应重点提高舰船航姿测量精度,其次提高风速和气压测量精度。

To improve shipboard gun’s hit precision, simulation research is done based on the ballistic equation of shipboard gun, the goal is to analysis effects on hit precision of the ship movements and meteorological parameters such as ship heading, attitude, velocity, sea area pressure, temperature, wind velocity, and determine the key factors. The simulation results show that hit position error overpasses 80 meters due to ship heading or attitude error of 0.5°, 30 meters due to wind velocity error of 1m/s, 20 meters due to pressure relative error of 1%. It can be concluded that the key point to raise the hit precision of shipboard gun is to increase ship heading and attitude, wind velocity and pressure determination accuracy.
