摘要
为了能够将弹丸在某一时间段内的飞行姿态实时再现,提出采用弹道同步跟踪反射镜技术,在摄像机前放置一面跟踪飞行弹丸的转镜,将弹丸的运动状态实时反射于高速CCD摄像机内.设计了弹道同步跟踪系统,给出了主要元件摆放参数,做出反射转镜转角及角速度随时间变化曲线.针对弹丸速度为1000 m/s、垂直距离为50 m,计算出弹丸速度的最大离散间隔为10 m/s,扫描速率为20等关键参数并进行仿真,结果证实本系统的可行性.
In order to represent the flying attitude of projectile in a certain period of time, using reflector vehicle tracking technology is used. A reflector vehicle is placed in front of the CCD camera to reflect the real-time attitude to the CCD, which can be achieved continuous photographing of projectile flying in exterior ballistics. Ballistics synchronous tracking system is designed, the placement parameters of major component is given,the curve of rotating reflector angle with time is ploted. While the velocity of projectile is 1000 m/s and stand off is 50m,the key parameters are calculated, the maximum discrete interval is 10 m/s and scan rate is 20. The system is simulated and the method is confirmed feasible.
