天幕靶灵敏度标定方法研究

天幕靶探测灵敏度是天幕靶重要的性能指标,目前使用的天幕靶灵敏度标定方法和表征参数不能准确的表征天幕靶的灵敏度.分析了天幕靶的工作原理和灵敏度机理,给出了光学镜头参数、被测弹丸长度与灵敏度之间的关系公式,提出了一种用小口径弹丸标定灵敏度的方法,推导了倍弹径数标定修正公式.通过气枪弹试验验证,研究的标定方法可行,给出的倍弹径数对实际使用具有明确的指导意义.

Study of the Sensitivity Calibration Method for Sky Screen

The detection sensitivity is an important performance index of the sky screen target.The curreat sensitivity calibration method can not achieve accurate sensitivity of the sky screen target.The paper analyzes the working principle and sensitivity mechanism.The relation formula of the sensitivity with parameters of the optical lens and the length of the measured bullet was established.A new method was presented that a air gun bullet was used to determine the sensitivity of the sky screen with parameter times diameter of the bullet.And also,the correcting formula of the parameter times diameter of the bullet was given.The air gun bullet experimental testing verified the feasibility of the method it is proved that the parameter times diameter of the bullet is useful in the weapon testing and proving ground.
