On Closed-Loop Spotting for Close Antimissle Naval Gun Weapon System

为了满足抗击反舰导弹的要求,近程反导舰炮武器系统必须大大提高射击精度,闭环校射是提高射击精度的有效途径。为了保证闭环校射的效果,必须获得精确的脱靶量测量值,建立有效的脱靶量预测模型。研究了适合近程反导舰炮武器系统的脱靶量测量方法。从闭环校射角度出发对射击误差进行了分类,利用tf时刻脱靶量将机动误差和外部误差引起的脱靶量进行了分离,利用近程反导舰炮武器的弹道特性,从测量获得的脱靶量中求出tf时刻脱靶量。最后,利用最小二乘滤波建立了脱靶量预测模型并进行了仿真计算。

In order to meet the requirements of opposing anti-ship missile, close-in antimissile naval gun weapon system must greatly improve its firing accuracy, while closed-loop shooting method is an effective approach to improve firing accuracy. In order to ensure the effect of closed-loop shooting method, the accurate measuring data of miss parameter must be acquired, and the effective prediction model of miss parameter must be built up. The miss parameter measurement methods suitable for close-in antimissile naval gun weapon system were studied. The firing errors were classified from the point of view of closedloop shooting, and the miss parameters of mobile error were separated from the miss parameters of external error by means of miss parameter at moment. By use of ballistic characteristics of close-in antimissile naval gun weapon system, the miss parameter at moment was obtained from measured miss parameter. Finally, the prediction model of miss parameter was set up by use of least square filtering method, and the simulation calculation was performed.
