摘　　要：弹丸的着靶坐标一直是身管武器外弹道测试领域经常测量的参数,针对现有六光幕阵列天幕立靶存在的系统复杂,主探测器比较笨重的问题,提出一种集成化双N型六光幕立靶测量方案,在每台主探测器的一个光学镜头内集成三个探测光幕,两台主探测器在空中形成两个N型的三光幕探测阵列。当弹丸依次穿越六个探测光幕,对应的两台主探测器三光幕天幕靶的电路依次输出六个弹丸信号,采用数据采集仪对弹丸信号进行采集,并通过弹丸信号处理算法对采集到的弹丸信号进行处理,得到弹丸穿越六个探测光幕的时刻值,再进一步通过对应的探测光幕参数和靶距参数计算得到弹丸的着靶坐标值。对系统着靶坐标测量误差进行了分析,并通过两种不同口径的实弹测试验证了系统的弹丸着靶坐标测量精度。The target coordinates of the projectile have always been the parameters that are often measured in the field of external ballistic testing of barrel weapons.Aiming at the problems of complex system and heavy main detector of the existing six light screens array sky screen vertical target,an integrated double-N-type six light screens vertical target measurement scheme is proposed.Three detection light screens are integrated in an optical lens of each main detector,and two main detectors form two N-type three light screens detection arrays in the air.When the projectile passes through six detection light screens in turn,the corresponding two main detectors are equipped with the circuit of three light screens sky screen target outputs six projectile signals in turn.The projectile signals are collected by the data acquisition instrument,and the collected projectile signals are processed by the projectile signal processing algorithm to obtain the time value of the projectile passing through the six detection light screens.Further,the target coordinates value of the projectile are calculated through the corresponding detection light screen parameters and target distance parameters.The measurement error of the system's target coordinate is analyzed,and the accuracy of the system's projectile target coordinate measurement is verified by two different kinds of caliber live ammunition tests.
