光电经纬仪目标运动特性模型构建方法研究

Research on Target Motion Characteristic Model Construction Method for Photoelectric Theodolite

分析了构建导弹、航天飞行试验任务中光电经纬仪所跟踪测量目标运动特性模型的必要性,提出用三次B样条曲线拟合弹道曲线并对目标运动姿态进行控制。为方便设计及应用,采用了不同的坐标系并给出相互转换公式。将目标弹道曲线、运动姿态、相对时间与特征事件等信息进行封装处理获得目标运动特性模型,用于光电经纬仪实战化训练。

Analyze the necessity of constructing the motion characteristic mode of the target that photoelectric theodolites tracking and measuring in missile and space flight test missions.Proposing use cubic B-spline curve to fit the ballistic curve and giving a mothed to control the target′s motion attitude.For the convenience of design and application,different coordinate systems are used and the mutual conversion formulas are given.Encapsulating the target trajectory,motion attitude,relative time and feature events to obtain the motion characteristic model for the training of photoelectric theodolites.
