常规的立靶测量装置要求弹道垂直预定靶面,当弹道不垂直预定靶面时,得到的测量结果是错误的。在终点弹道,有时很难保证靶面垂直飞行弹道。提出了一种由多光幕阵列组成的光幕立靶,可以实现小于70°入射角的弹丸着靶坐标的测量,不要求飞行弹道垂直靶面。在X和Y方向分别采用四个成固定角度的光幕来实现入射角度的测量,一次射击可得到弹丸的速度、速度方向上的空间角和着靶位置坐标。 Conventional target-setting measuring devices require a ballistic target surface to be perpendicular. When the ballistic trajectory is not perpendicular to a predetermined target surface, the measurement result obtained is erroneous. Ballistic at the end, it is sometimes difficult to ensure the vertical flight trajectory of the target. A multi-curtain array of light curtain targets is proposed to measure the target coordinates of the projectile at angles of incidence less than 70 °. The vertical trajectory of the flight trajectory is not required. In the X and Y directions were used to achieve a fixed angle of the light curtain to measure the angle of incidence, a shot can be obtained projectile speed, the speed of the direction of the spatial angle and the target position coordinates.
