模拟训练系统中的激光驾束制导导弹弹道仿真

摘要

The motion and control capability of laser beam riding guidance gun launched missile is analyzed based on the characteristics of missile and simulated training. In a laser beam coordinate system, missile motion is decomposed into the axial motion and radial motion. Through the coordinate transformation matrix, the coordinates of the missile is transformed from the earth coordinate system to sight coordinate system. Under the control conditions, the missile flight control mode is established. Hit detection model is established based on the target size and visual simulation program operating characteristics. All lliese models are coded and applied in the training system of ballistic missile. The result indicates that these models are practical and meets ihe real-time visual simulation system requirements and ensures the authenticity and validity of simulation training.%针对激光驾束制导导弹的制导原理和模拟训练的特点,对导弹的运动及控制特性进行了分析.在激光束坐标系下,将导弹的运动分解为沿激光编码场轴向的运动与沿激光编码场径向的运动,建立了导弹的运动学模型.通过坐标转换矩阵,将导弹坐标从大地坐标系转换到瞄准镜坐标系中,并根据受控判断条件建立了导弹的飞行控制模型.根据目标尺寸特性和视景仿真程序的运行特性,建立了命中检测模型.在实际工程中对上述模型进行了编码实现,应用于基于虚拟现实技术的炮射导弹瞄准手模拟训练系统.试用情况表明,该模型实用性强,满足视景仿真系统实时性的要求,能够保证模拟训练的真实性和有效性.
