线激光平行检测阵列弹幕武器弹着点测试方法

Measuring method for barrage weapons dispersion by line laser parallel detector array

  • 摘要: 针对弹幕武器的立靶密集度测试难题,提出了一种基于线激光平行检测阵列组合的测试方法。研究了在平行检测阵列结构下实现弹丸定位的测量原理,推导了弹着点坐标解算公式,给出了弹着点坐标解算的程序流程,并分析了检测阵列精度导致的输出误差,研究了坐标计算误差与坐标位置及靶面大小的分布关系。当规则靶面面积从3 m3 m扩展到10 m10 m时,排除极小部分高误差区域后的x坐标固有误差绝对值从1.56 mm变成5 mm,增加了3.44 mm,y坐标测量固有误差为2 mm。对规则靶面面积为1 m1 m样机的模拟坐标测试结果表明,当采用的阵列精度为1.6 mm时,x坐标最大误差为3.6 mm,y坐标最大误差为2.8 mm。该测试方法有效光幕面积大、测量精度高、布靶难度小。

     

    Abstract: A high precision laser screen dispersion measurement method based on the line laser parallel detector array composite was presented to solve the difficulty of barrage weapons location dispersion test. The principle of measuring shell coordinate based on line laser parallel detector array composite was researched. Impact points coordinate algorithm was derived and the impact points coordinate algorithm flow chart was presented. Algorithm errors caused by laser detector array precision was analyzed, coordinate errors distribution of coordinates positions and target area were researched. The analysis results indicate that maximum theoretical x negative innate errors increases by 3.44 mm, from 1.56 mm to 5 mm and the maximum y innate errors was 2 mm when the regular target area increased from 3 m3 m to 10 m10 m unless small area with high errors. Tests have done with the proto whose target area was 1 m1 m, the results show that the maximum x errors was 3.6 mm, and the maximum y errors was 2.8 mm when the precision of detector array was 1.6 mm. This measuring method has the advantages of high measuring precision, easy to construct large target area, easy to install.
