摘　　要：为研究飞行弹丸斜入射时着靶坐标测量原理误差的分布规律,根据四光幕精度靶几何结构,建立了斜入射下着靶坐标测量原理误差模型,研究有效探测靶面内不同着靶位置与不同入射角下原理误差分布规律;分析工程应用中发射位置确定下,不同散布半径与不同射击距离对测量原理误差的影响,给出着靶坐标测量的修正公式,并进行实弹射击试验。试验结果表明:飞行弹丸斜入射时必然存在原理误差,必须修正着靶坐标;射击距离一定时,发射枪散布半径越大,原理误差越大;散布半径确定时,原理误差随射击距离增加而减小;在发射位置确定下,采用修正公式后,四光幕精度靶测量误差小于1 mm。In order to study the distribution law of the principle error of impact coordinate measurement for an obliquely incident projectile,a principle error model of impact coordinate measurement under oblique incidence is established according to the geometric structure of four-light-screen optical target.The distribution law of the principle errors at different impact positions and different incidence angles in the effective detection light-screen plane is studied.The influences on different dispersal radius and different shooting distances on the measurement principle error at the determined shooting position in engineering application are analyzed,and the correction formula for the measurement of impact coordinates is given.The shooting test was carried out.The results show that:the principle error inevitably exists when the flying projectile is obliquely incident,thus the impact coordinate should be corrected.At a certain shooting distance,the larger the gun’s dispersal radius is,the larger the principle error is;when the dispersal radius is determined,the principle error decreases with the increase in shooting distance;under the determination of shooting position,the measurement error of four-light-screen optical target is less than 1 mm after using the correction formula.
