摘要
立靶测量是射击训练及射击比赛中一种常用的弹着点位置测量方法,弹道俯仰角是立靶测量的重要参数之一,其偏差水平是影响测量精度的重要因素.重武器弹丸入射时由于重力、地形等各种因素的影响,使弹丸产生弹道俯仰角,因此以弹丸垂直入射为假设条件的传统T型报靶模型不再适用.针对上述情形,本文以单个激波传感器全向入射理论为基础,提出基于6 个激波传感器组成H型阵列的弹丸全向入射弹着点定位模型,解决传统T靶模型传感器数目少、无法求解俯仰角与方位角的问题,以提高测量的精度.对该模型进行数学推导与仿真分析,并应用到靶场实验中进行验证.实验结果表明,通过该模型计算出的弹着点坐标与实际弹着点坐标相比误差较小.因此,该模型能够有效减小弹道俯仰角对报靶系统的影响,更具实用价值.
Abstract
The vertical target measurement is a commonly used method for measuring the impact point position in shooting training and shooting competitions.The elevation angle of the projectile is an important parameter in vertical target measurement.And its deviation level is a significant factor affecting measurement accuracy.In the case of heavy weapons,the projectile trajectory is affected by factors such as gravity and terrain,making the traditional T-shaped target model,which assumes vertical projectile impact,no longer applicable.In response to this situation,based on a single shock wave sensor′s theory of omnidirectional incidence this paper proposes a positioning model of pro-jectile omnidirectional impact point with a H-shaped array of six shock wave sensors.It solves the problem that the traditional T-target model has a small number of sensors and is unable to solve the pitch and azimuth angles,and improves the accuracy of the measurement.The mathematical deriva-tion and simulation analysis of the model are conducted,and it is validated through field experi-ments.The experimental results show that the calculated impact point coordinates using this model have small errors compared to the actual impact point coordinates.Therefore,the model can effec-tively reduce the influence of the ballistic pitch angle on the target reporting system,which is more practical value.
