针对进口设备B571光学靶测试系统后端信号采集与处理部分故障后无法工作的问题,设计了一种采用数据采集装置的技术升级方案.方案包括硬件、软件和结构参数识别算法,硬件包括四通道数据采集装置和信号隔离仪,通过软件实现弹丸过幕信号的数据采集与处理,采用识别算法获取光学靶光幕探测传感器阵列结构参数.改造后的硬件和软件配合B571光学靶光幕探测传感器阵列,实现小口径弹丸射击密集度参数测量.实弹射击对比结果表明:射击密集度参数的测试误差小于1mm,满足实际靶场试验要求.文中研究的方法可以用于一类四光幕阵列光学靶的技术改造或升级.

While the signal processing of B571 optical target measurement system of an imported device failed to work normally,an technology upgrading program based on the data acquisition equipment is designed.The solution includes the hardware,the software and the algorithm of identifying the structure parameters.The hardware includes the data acquisition equipment and the signal isolation instrument for four channels.The special software is used to acquire and process the projectile signals.The identifying algorithm identifies the structure parameters of the B571 optical target.With the detecting array of B571 optical target light-screen,the improved system achieves the measurement of firing dispersion parameters of small caliber projectiles.The result of field firing shows：Compared with the paper target,the errors of the firing dispersion parameters of the upgraded system are less than 1mm.The solution can be used for technical transformation or upgrading of a kind of four-light-screen array optical target.
