立靶精度测试系统的光纤标定和误差分析

Optical fibre calibration and error analysis on a fire measuring system

立靶精度测试系统的功能之一是准确测出直射武器的立靶坐标．根据系统测量原理，建立了立靶测量公式．又以微分法为基础，分析并计算了系统的理论误差．对光纤的标定结果表明，系统的理论误差明显降低，满足了设计要求，将立靶精度测试系统与纸靶测量法经靶场实弹射击进行了对比，证明本系统误差的理论分析是正确的。

One of the functions on a fire accuracy measuring system is that shooting bullets coordinates can be measured accurately and automatically. Based on measuring principle, the calculating formula is presented, also, the theory errors of the system are analyzed and calculated. By means of optical fibre calibration, the system errors are reduced dramatically and satisfy design needs. By two group bullets live ammunition shooting, compared with the paper board measuring system, the fire accuracy measuring system is proved that the errors analysis is correct, and the measuring accuracy is less than one half of shooting bullet diameter.
