摘要
针对空中目标脱靶量高精度测量需求,提出了一种基于同帧画幅空中脱靶量的光学测量精度评估方法.根据同帧画幅双目标测量特点以及脱靶量测量误差相关性,对脱靶量测量误差组成进行了分析,构建了脱靶量误差指标体系;根据同帧画幅脱靶量计算过程及武器系统误差传递相关性,分析光学交会测量定位误差,建立空中脱靶量光学测量误差传递模型,并计算测量设备对各测量值的误差传递系数以及对空间x、y、z三方向脱靶量误差的贡献度.仿真结果表明,测量设备随机误差范围小于10",脱靶量计算精度可达到米级,满足空中目标脱靶量高精度测量要求,可为空中脱靶量光学测量精度评估提供理论依据.
Abstract
Aiming at the requirement of high accuracy assessment of aerial target miss distance,an evaluation model of the miss distance measurement accuracy in the same frame is established.According to the characteristics of the same frame target measurement and the correlation between the miss distance measurement,the error composition of the miss distance measurement is analyzed.According to the measurement method of miss distance in the same frame and the correlation of error transfer in the weapon system,the optical rendezvous position error is analyzed and the space miss distance error is established.At the same time,the error transfer coefficient of the measuring equipment to each measurement value and the contribution degree of each measuring equipment to the three-direction miss distance in space are calculated.The total error of aerial miss distance is determined.The proposed method can provide a theoretical basis for the optical measurement evaluation of the aerial miss distance.
