摘要/Abstract

摘要： 针对光电立靶光幕阵列结构参数标定误差较大的问题，提出一种光幕阵列结构参数反演优化的方法。以测量坐标与纸板靶坐标差值的平方根构建目标函数，借助正交试验在允许误差范围内产生多组不同参数量值的组合，设计了光幕阵列结构参数优化方法。以双N形天幕靶为例，在Matlab中进行仿真，优化后的光幕阵列结构参数更接近给定真值，且结构参数的优化程度与标定的初始值和误差范围相关。用实弹射击试验对设计的方法进行验证，结果表明，优化后的弹丸飞行参数测量结果更接近实际真值，设计的方法有效可行。该优化方法为提高光电立靶测量设备的测量精度提供了一种新思路。

Abstract: An optimization method for inversion of light-screen-array structure parameters is presented for their large calibrated errors. An objective function is established by using the square root of difference between measuring coordinates and actual coordinates, many groups of structure parameters are generated within the allowable error range based on orthogonal test, and the optimization method of light-screen-array structure parameters is designed. The simulated results of double-N shaped sky screen target in Matlab shows that the optimized results are affected by the initial value and the allowable error range, and the ball cartridge test results show that the proposed method is feasible and effective. The optimization method provides a new idea for improving the measuring accuracy of photoelectric target measuring equipment. Key
