摘　　要：为了改善飞行弹丸立靶坐标测量系统的布置复杂、集成度低等缺点,提出了2种新型天幕靶的设计方法;根据立靶坐标的几何测量原理,采用单镜头双狭缝措施,设计了单镜头双狭缝交汇和单镜头双狭缝平行的天幕靶.利用两镜头构建了多光幕交汇测量弹丸坐标模型,采用高响应、低噪声阵列长条形光电探测器件,简化天幕靶结构设计,改善天幕靶探测性能.结合多光幕交汇测量系统数学模型,应用微分法分析了测量系统误差.靶场实弹试验结果表明,设计的2种新型天幕靶可以实现飞行弹丸坐标的测量,在高空大靶面条件下,坐标测量误差小于20 mm.In order to overcome the shortcomings of complicated organization and small density of vertical target measurement system of projectiles,the design methods of two types of sky-screens were proposed.Based on the geometric measurement principle of vertical target coordinate,the methods of single lens with two slits that were intersect and parallel was employed to design sky-screen,and its design principle was analyzed.The multi-screen across measurement system used to test projectile coordinate was constructe...
