多站遥测数据处理中的数据融合方法研究

Research on Data Fusion Method for Multi-Station Telemetry Data Processing

针对某型号火箭上升段遥测结果显示中断现象,分析问题原因,结合数据特征提出多站遥测原码数据融合处理措施。试验数据处理结果表明,相对于单站处理和多站结果融合处理,提出的多站原码融合处理更具优越性,它更利于实现,可同时保证测量信息的高效利用和处理结果的准确可靠,能够满足飞行试验指挥决策和评估鉴定需求。

A multi-station telemetry source data fusion method which has considered the data characteristics is proposed on the basis of analysis of telemetry data interrupt at the ascent stage for one particular rocket flight test.The test data processing results demonstrate the superiority of the proposed multi-station source data fusion method.Compared with the single station processing and multi-station results fusion,the multi-station source data fusion is easier to implement,and it can obtain the effective utilization of measurement data and correctness of processing results,which meets the requirements of command decision and flight test evaluation.
