摘　　要：基于立靶坐标交汇测量原理,介绍了传统单线阵CCD立靶系统,并对单线阵CCD立靶系统中弹丸攻角测量方法进行了分析,指出了其中存在的扫描帧频不足和弹头、弹尾着靶点距离误差的问题。在此基础上,提出了一种新的多阵列光电立靶测量系统的布设方法,利用6个交汇列图像在空间交汇组成光幕阵列,根据飞行弹丸穿越不同光幕阵列的时刻和多光幕立靶系统结构参数,提出了一种新的计算弹丸攻角的方法。利用多线阵光电立靶测量系统巧妙地避免了弹头、弹尾着靶点距离误差对测量结果的影响,保证了测量精度,降低了系统成本。Traditional vertical target system of single-linear array CCD based on measuring principle of coordi- nate-intersection is introduced, and attack angle measurement method of projectile in single-linear CCD vertical target system is analyzed. Problem of shortage is mainly caused by low scanning frame rate and error in measuring position of head and the tail-end of projectile on target is pointed out. On this basis, a new layout method for multi- linear array vertical target system is put forward to measure attack angle of projectile, six images of vertical image are used to construct light screen array, a new measuring method is proposed based on time that projectile go through different light screen array and structure parameters of multi light sceen vertical target system. Using the multi-linear vertical target system avoid influence of error in measuring position of head and the tail-end of the projectile on measurement result. Assure measurement precision and reduce system cost.
