摘要
在研究自相似理论的基础上,通过SELFIS工具中的Whittle最大似然估计法对航天器遥测数据进行自相似分析,以一个遥测点数据为例估算其Hurst参数,并对分析结果做出详细解释.实验结果表明大部分遥测点数据都具有自相似性,为遥测数据自相似仿真模型的建立奠定了基础.
On the basis of the study of the theory of self-similarity,the self-similarity of spacecraft telemetry data is studied by the method of Whittle maximum likelihood estimation in the SELFIS tool.The paper takes the data of a Telemetry point as a example.Its Hurst parameter is estimated with a detailed explanation.The experiment results show that the majority of telemetry data has self-similarity,which lays a foundation for the establishment of self-similarity simulation model of telemetry data.
