摘要
为了能够实现弹道高度的自动化测量,用天幕靶对应的四个光幕面在空中形成具有一定几何关系的光幕阵,弹丸以一定的角度穿过天幕靶对应的四个光幕面时,数据采集仪采集四个天幕靶输出的弹丸模拟信号,并用相应的算法对信号进行处理和分析,得到弹丸穿越四个光幕的时刻值t1,t2,t3,t4,根据这些时间间隔和系统的结构参数求出弹丸撞击光幕面对应点距离地面的高度.
Four sky screens are used to form a certain screen array in space for measuring the height of the bullet trajectory. When the bullet flights through the four screens of the array at any direction, the data collecting instrument records the data of the analog signals produced by the sky screen. The data acquired are analyzed and processed by the arithmetic program, then the flying time t1 , t2, t3 , t4 of the bullet through the light screens can be calculated. The height of the bullet trajectory can be got by the times and the systemic structural parameters.
