三种着靶坐标自动测量设备精度评价方法

摘要

The automatic measurement system of projectile impacting coordinates has widely applied in the measurement of density of the barrel weapons,the measuring results often need to be compared with paper target results to evaluate the precision,in the course of equipment production and development.It is independent of automatic measurement system and paper target,but the two sets of results cannot be compared directly,which brings difficulties for the accuracy assessment of automatic measurement system.Because of the center of the scatter of projectiles,the relative position between projectiles and the base point,the systematic difference of two coordinate systems are constants,this paper introduced the principles,processes and results of three methods,than verified by the field experiment.The conclusion can provide useful reference for accuracy assessment of automatic projectile impact coordinates measurement system.%弹丸着靶坐标自动测量设备在身管武器的密集度测量中应用广泛.在该类设备的生产、研制过程中常需将其测量结果与纸板靶测量结果进行对比,以评价该类设备测量精度.评价试验中,自动测量设备与纸板靶坐标系统相互独立,两套系统的测量结果不能直接比对,给自动测量设备的精度评价带来困难.本文分别从弹丸散布中心、弹丸与基点距离和坐标系系统差的角度研究了3种评价方法,介绍其原理和过程,并通过实弹试验数据完成了对3种评价方法的验证和比较.文中结论可为着靶坐标自动测量设备的精度评价提供方法和参考.
