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 ,利用此方法可以解决狭缝像机不能实时测量的问题 A new method to measure the angle of attack of the projectile is proposed. The use of linear CCD camera intersection to form a light target, measuring the instantaneous position of the projectile through the light target, the obtained position information arranged in time sequence can be obtained after the projectile angle of attack. Firstly, the principle and feasibility of measuring the angle of attack of the projectile using a line CCD camera are analyzed. Based on the analysis, the composition and function of the measuring system to achieve this goal are proposed. Then the measuring accuracy of the angle of attack Analysis and discussion. The results show that under the premise of the current CCD slit camera does not have the practical application conditions, this method can solve the problem that the slit camera can not measure in real time
