摘要
遥测数据丢帧严重影响试验的有效性,在丢帧原因分析的基础上,归纳出明文数据和密文数据两种丢帧统计方法,并提出基于帧计数判断和帧时码判断两种数据融合策略。采用权系数融合算法对多流遥测数据的融合处理进行了研究,以提高数据的完整性和可靠性,在实际任务中,验证了融合方法的有效性。
The validity of experimentation is impacted badly by frame-losing of telemetry data of missile, two statistic methods of frame-losing of unencrypted data and encrypted data are concluded based on the analyzing of the reasons of frame-losing. Two strategy of data-syncretizing are advanced based on the count-estimate and time-estimate of the frame. Also, the fusion of telemetric multi-data is researched to enhance the integrality and reliability of telemetry data by the method of weighted data fusion. The meth- od of the fusion of telemetry multi-data is validated by the practical mission.
