摘要/Abstract

摘要： 主要针对破片速度测量实际需求,建立了光幕靶测量数据处理方法和速度误差的传递模型。研究了着靶信号波形匹配技术和破片轨迹匹配技术,利用无偏估计给出了测时、测距等各测量参数的随机误差范围,再结合时间和距离的匹配误差,最终给出了破片速度测量的总误差。

Abstract: Aiming at the actual requirements of fragment speed measurement,a method for the processing of light screen target measurement data as well as a speed error propagation model are developed.The matching technology of both the target signal waveform and the fragment orbit is studied.Based on the unbiased estimation,the scopes of random error for parameters such as time and distance are determined.And the total error of fragment speed measurement are given with considering the time and distance matching errors.

Key words: light screen target, fragment, speed, match, perforation
