弹目偏差仿真系统的设计与实现

Design and Implementation of Miss Distance Simulation System

在虚拟闭环校射中,为了减小使用直线线性插值求取迎弹面上的弹着点引起的误差,采用三次样条插值求取弹着点。仿真系统基于Vega Prime软件并结合MFC人机界面将校射过程可视化,使用Multigen Creator对高炮、直升机和戈壁滩地形进行建模,模拟高炮对直升机的拦截过程。仿真系统接收火控计算机观测所得的目标航路和弹道模拟器解算的弹道数据,使用样条插值方法求取弹目偏差,实时返送给火控计算机,形成虚拟闭环较射。该仿真系统具有画面直观逼真等优点,可为相关闭环校射视景仿真的开发研究提供参考。

In the virtual closed-loop calibration,in order to reduce the error caused by the linear point interpolation to obtain the impact point on the ballistic surface,the cubic spline interpolation curve interpolation was used to obtain the impact point.The simulation system was based on Vega Prime software and combined with the MFC human-machine interface to visualize the calibration process.Multigen Creator was used to model the terrain of the anti-aircraft artillery,helicopter and the desert to simulate the interception process of the anti-aircraft gun.The simulation system received the ballistic data calculated by the target route and the ballistic simulator observed by the fire control computer,and used the spline interpolation method to obtain the bullet deviation,and returns it to the fire control computer in real time to form a virtual closed loop.The simulation system has the advantages of intuitive and realistic picture,and provides a reference for the development of related closed-loop calibration vision simulation.
