摘要

    摘要
  • 摘要: 针对现有的天幕靶幕面空间位置参数检定方法需要拆卸的不足，提出一种不拆卸天幕靶对其探测幕面位置检测的方法。以经纬仪建立基准面，采用放置在基准面内特制的频闪小光源和设定天幕靶输出阈值的方式，根据小光源作用在天幕靶上有信号输出时平移台相对基准面的移动距离，实现天幕靶幕面空间位置参数的检测。将天幕面相对基准位置倾斜2、-2、-5时，所测幕面倾斜角度与实际幕面倾斜角度间误差均小于1，试验结果表明天幕靶幕面位置检定方法精度优于1，与理论分析相一致。该方法不需要拆卸天幕靶，节省了时间，能用于使用中天幕靶的检定。
    Abstract: Due to the requirement of disassemble for existing sky screen position detection method in flying projectile, a novel position detection method was proposed without dismantling the flying projectile. At first, the theodolite was used to build the datum plane. In the second, by using the specified stroboflash tiny illuminant and setting the output threshold of sky screen, based on the relative displacement distance between the transition table and the datum plane while the output signal of illuminant was showing on the sky screen, the relative position parameters were detected. Finally, when the sky screen tilted 2,-2 and -5,the error of measured tilted angle and actual angle was always less than 1, the experiment results showed that the detection accuracy was more than 1 which agreed with the theoretical analysis. The proposed method does not require the disassemble of the flying projectile, it saves the time and can be further used in the position measurement of fly projectile.
