摘要

In the three dimensional flight simulation system of anti-radiation weapon attack or analysis of 3D motion data,the traditional motion of rotation method exits in calculation complated and have balance ring locking limitation. Quaternion method can avoid these limitations and have clear geometric meaning with simple calculation,therefore this paper puts forward quaternion method to achieve motion attitude and flight velocity vector rotation in the anti-radiation weapons flight simulation system and realize the reasonable effect of flight attitude anti-radiation weapons are smooth and continuous change in anti-radiation weapons flight simulation,The results of application show that the quaternion method can improve the calculation efficiency and apply in flight simulation of anti-radiation weapons.%在开发反辐射武器攻击目标的三维飞行仿真系统中或分析处理三维运动数据时，针对传统的运动姿态旋转方法存在计算繁琐、旋转不均匀性及平衡环锁定等局限问题，采用四元数法可以避免这些局限，并且几何意义明确，计算简单。因此，提出在飞行仿真系统中利用四元数法来实现反辐射武器的运动姿态及飞行速度矢量的旋转，在飞行仿真试验中实现了飞行轨迹变化光滑连续的合理效果，仿真结果表明四元数法简化了矢量旋转计算模型，优化了解算性能，能够很好地应用于反辐射武器飞行仿真试验中。
