摘要
特征事件综合和弹道融合是航天发射过程中最为重要的一项工作,通过特征事件发生时间和火箭飞行弹道可直观地反映出运载火箭的飞行状态.因此,为了进一步提高特征事件综合和弹道融合效果,基于遥、外测量信息,分别对参与特征事件综合和弹道融合的信息源进行分类及其影响因素进行分析,并提出了相应的信息融合策略.通过采用优化的融合策略,可进一步提高特征事件时间解算的准确性和实效性,提升弹道融合的效果,满足航天发射飞行态势显示和安全控制的任务需求.
Abstract
Feature event synthesis and ballistic fusion are the most important tasks in the process of space launch.The flight status of a launch vehicle can be intuitively reflected through the occurrence time of feature event and its flight ballistic trajectory.In order to further improve the effectiveness of feature event synthesis and ballistic fusion,based on the remote and external measurement information,the information sources involved in the feature event synthesis and ballistic fusion are classified,their influence factors are analyzed,and the corresponding information fusion strategies are proposed.By adopting an improved fusion strategy,the accuracy and effectiveness of the feature event time calculation is further improved,and the ballistic fusion results are improved enough to meet the requirements of status display and safety control missions during the space launch flight.
