弹丸章动周期的光学立靶测量法

Measuring Nutation Period with Non-contact Vertical Target

提出了一种新的测量弹丸初始弹道章动周期的方法 ,采用非接触式光学立靶测量原理测量弹丸章动周期 测量弹丸通过立靶的瞬时位置 ,计算出弹丸章动角 ,根据多组章动角数据获得弹丸的章动周期 并提出了实现这一目标的测量系统的组成与功能 。

A new measurement method for nutation cycle has been put forward with the measuring theory of non contact vertical target. After instantaneous position arranged by time sequence is measured where missile or cannonball passing through the light target, the nutation angle can be calculated. According as nutation angle of variant position, the nutation period can be obtained. The constituion and function of measurement system for measuring the nutation angle have been put forward.
