Abstract

The invention provides a method for dividing multiple remote sensing parameter analyzing windows of a spacecraft. Through analyzing a multiple-remote-sensing-parameter association period and selecting a reference parameter acquisition dividing characteristic, accurate dividing for multiple parameter analyzing windows in a manner of alignment in a time scale is realized. According to the method of the invention, analyzing window dividing is performed through a remote sensing parameter reference dividing characteristic instead of a fixed or a slidable window, thereby preventing window drift caused by factors such as space environment and channel transmission, realizing accurate dividing of the remote sensing parameter analyzing windows and improving accuracy of subsequent characteristic extraction and diagnosis detection. According to the method of the invention, synchronous dividing is performed on a plurality of remote sensing parameters through the reference parameter; window alignment in the time scale is realized; analyzability of the remote sensing data is improved; and analyzing and digging of an association relation between multiple parameters are facilitated.

Description

technical field

[0001] The invention belongs to the field of spacecraft telemetry data analysis, and in particular relates to a multi-telemetry parameter analysis window division method of a spacecraft. Background technique

[0002] With the development of information technology, fault feature extraction and diagnosis technology has been greatly developed in the field of spacecraft telemetry data analysis. Among them, determining the feature analysis window is a basic problem in the analysis of spacecraft telemetry data, which directly determines the accuracy and reliability of feature extraction and diagnostic detection.

[0003] At present, the multi-telemetry data analysis of spacecraft mostly uses fixed windows or sliding windows to divide each parameter into multiple analysis subsequences in turn. There are two problems in this division method: First, due to the maneuvering characteristics of the spacecraft and the complexity of the space environment, it is difficult t...
