摘　　要：火炮跳角是射角的组成部分,初速矢量与发射前身管轴线之间的夹角称为跳角.跳角是射表的基础数据,对射表精度有重要影响,跳角又是影响火炮射击精度的关键参数之一.靶板法是目前广泛采用的火炮跳角测量方法,在炮口前面给定靶距位置竖立一面靶板,火炮射击,弹丸在该靶板上留下弹孔,弹孔中心与靶板上瞄准中心之间的偏差量就表示跳角大小.由于靶板法不能满足大射角测量和测量效率低等固有缺陷,人们又提出了PSD法、线阵CCD立靶法、陀螺仪法和重叠法等改进方法.因改进方法存在抗过载性能较差、出现漏测、或只能得到相对量等多种缺陷,目前还没有在火炮工程实践中得到推广应用.The angle between initial velocity vector and the barrel axial line before firing is called the jump angle which is the component of departure angle of gun. The jump angle is the foundation data of firing table, and it has an important influence on the precision of firing table. Therefore, the angle of jump is one of the key parameters affecting the firing precision. The method of target board is the measurement method of angle of jump of gun widely used presently. In this method, an upright target is fixed on a given position in front of the muzzle, and then projectile hole is left on the target board after the gun has fired. The deviation between the center of projectile hole and the aiming point on target board can be considered as the value of angle of jump. It can be noted that the method of target board is incapable in the high angle of departure situation and the measurement efficiency is very low by using this method. For the disadvantages above, some modified methods have been proposed, such as PSD method, linear array CCD vertical target method, the gyroscope method and overlapping method. The shortage of these modified methods can not be ignored, such as lacking the overload-resisting capability, missing the measurement data, or only obtaining the relative quantity mea- surement. For these reasons, the modified methods have not been widely used in engineering practice.
