天幕靶测速精度分析

PRECISION ANALYSIS FOR MEASURING THE VELOCITY OF PROJECTILE BY P.C.C

从实用角度出发，以ＴＭＢ－１型天幕靶为对象，就其测量弹丸水平飞行速度的测量精度进行了详细分析．并得出结论：天幕靶测速精度不仅与仪器本身精度有关，而且还与使用方法以及试验条件有关。

The type TMB-1 P.C.C is focused on in this paper from the view of application.The author analyses its measurement precision of velocity for the horizontal flying projectile in detail, then draws the conclusion that precision of measuring velocity of projectile does relate not only to precision of instrument,but also to application method and experimental condition.
