| 摘 要： | 针对光电探测系统(EODS)的高精度指向要求,提出一种基于半参数同归模型(SPRM)的改进算法.全面分析了误差来源,如光学系统的光轴一致性误差、机械框架的垂直度和回转误差、控制系统的稳定跟踪误差等,采用多体系统运动学理论,建立了具有明确物理意义的指向误差线性模型.同时,针对系统中的非线性误差因素,提出了半参数回归模型改...

| Abstract: | An improved algorithm based on a semi-parametric regression model(SPRM) is proposed in this paper to achieve high accuracy pointing for electro-optical detection systems(EODSs).The error sources are analyzed comprehensively,which are mainly composed of consistency errors of the optical system,perpendicularity and rotation errors of the mechanical assembly,stability and tracking errors of the control system,etc.And then,the multi-body kinematics theory is used to structure a linear model with parameters of d... |
