基于改进弹丸追踪法的舰炮校射方法研究
|
摘要
根据外弹道模型的性质和校射的实际需求,利用NAGA-II算法实现了利用弹丸的跟踪数据对射击诸元的计算;仿真试验的结果表明:改进的弹丸追踪法校射在连续射击中能更有效地对射击结果进行修正,当连续射击次数足够大时,能使脱靶量绝对值降低约17%,提高射击精度。
According to the properties of external trajectory model,the principle of virtual extension of trajectory by using projectile tracking information and external trajectory model was discussed. According to the actual requirements of calibration,NAGA-II algorithm was used to calculate the firing elements by using the tracking data of projectiles. The simulation results show that the improved projectile tracking method can more effectively correct the firing result in continuous firing. When the number of continuous firing is large enough,the absolute miss distance can be reduced by about 17%,and the firing accuracy can be improved.
