Intersection Measuring System of Erecting Target with Dual Liner CCD

为了准确测量弹丸的立靶精度,本文采用了双线阵CCD交汇测量的方法。文中介绍了该方法的工作原理,推导出目标在光电靶上的坐标计算公式,同时分析和研究了各个测量模块的元器件和布站方式,从而构建了整个测量系统。最后在靶场进行了实弹试验,得出弹丸的立靶精度为0.0417m(方向公算误差)和0.0319m(高低公算误差),该测量值与标定值比较相差在毫米级,说明系统的测量精度十分理想。故该系统的研制是成功的,能够准确测量弹丸的立靶精度。

In order to accurately measure the target accuracy of the projectile＇s position,this article used the intersection measuring system with dual liner CCD and introduced the working principles of this system,and the calculated formula of target coordinates had been demonstrated.We analyzed the components and the positioning ways of each measurement module,on the basis of which the measuring system had been established.The target accuracy of the projectile＇s position is 0.041 7 m （Direction error probable） and 0.031 9 m （Level error probable）.The measured value compared with the calibration value in the mm level difference,indicates that the system accuracy is ideal.So the development of this measuring system is successful,and it was able to accurately measure the target accuracy of the projectile＇s position.
