现有的六幕光幕靶测量系统实现了近距离弹丸速度、姿态以及着靶坐标的测量,而在实际工程应用中需要计算的是弹丸整个飞行过程中的速度、姿态以及远距离的落点坐标。针对现有系统工程部署中的不足,提出了双交叉结构的六幕光幕靶的设计原理。利用双交叉结构的六幕光幕靶的测量结果以及外弹道计算原理,通过四阶龙格-库塔方程建立了弹道测量模型,实现了弹丸飞行全过程的弹道测量和计算。通过使用弹道系数1.0的标准弹丸进行仿真实验和分析,计算出其射程和射高分别可以达到16 269m和3 672m,证明了其与实际的弹丸运动曲线相吻合,能够实际应用于工程部署。
The existing six-screen light curtain target measuring system realizes the measurement of the projectile velocity, attitude and target coordinates in the near distance, and the actual projectile needs to calculate the velocity, attitude and long-range falling point of the projectile throughout the flight coordinate. In view of the shortcomings in the existing system engineering deployment, the design principle of six-curtain screen with double cross structure is proposed. The ballistic measurement model was established by using the fourth-order Runge-Kutta equation and the ballistic measurement and calculation of the entire flight of the projectile were achieved by using the measurement results of the six-cross curtain with double crossover structure and the calculation principle of the external ballistics. By using the standard projectile with a projectile coefficient of 1.0 to simulate the experiment and analysis, the calculated range and shot height of the projectile can reach 16 269m and 3672m respectively. It proves that it matches the actual projectile motion curve and can be applied to engineering deployment.
