使用Chapman-Kirk方法以及多项式拟合手段,对靶场试验中所得的BEL测速雷达数据进行处理,得到飞行过程中弹体的阻力系数,将其与风洞实验数据对比,分析飞行过程中系统偏差。
Using Chapman-Kirk method and polynomial fitting method, the BEL speed radar data obtained in the shooting range test are processed to obtain the drag coefficient of the projectile in the flight process. The drag coefficient of the projectile is compared with the wind tunnel experimental data to analyze the system deviation during the flight.
