Linear CCD array cameras intersect measurement for nutation angle

提出了一种新的测量弹丸攻角的方法。利用线列CCD像机交汇形成一光靶 ,测量弹丸通过光靶的瞬时位置 ,将获得的位置信息按时间序列进行排列后即可获得弹丸的攻角。首先分析了利用线列CCD像机交汇测量弹丸攻角的测量原理及可行性 ,在此基础上提出了实现这一目标的测量系统的组成与功能 ,然后对测量系统的攻角测量精度进行了分析和讨论。结果表明 ,在目前CCD狭缝像机还不具备实际应用条件的前提下 。

A new measurement method for nutation angle has been put forward. Using two line ar CCD array camera's visual field intersecting a light target, the instantaneou s position when missile or cannonball puts through the light target is measured, after the position information is arranged by time sequence, the nutation algle is obtained. The measuring theory and feasibility using two linear CCD array cam era intersectant measurement nutation angle are analyzed at fist, then the const itute and function for measurement system of measuring the nutation angle are pu t forward, at last the precision of measuring nutation angle using this measurem ent system is analyzed and discussed.
