Embodiment Construction

[0036] Existing data files can no longer meet the needs of data mining in terms of data storage and data updating. It is very necessary to build a database system that integrates multi-source data and can efficiently and quickly index and query. In view of the large amount of data, inconsistency of data, and the fatigue of traditional databases in data processing in the analysis of space missions, it is necessary to establish a statistical analysis method for space target data oriented to the simulation analysis of space system missions. Multiple formats and different types of multi-source massive space target data are used for data fusion, statistical analysis, and data mining to improve the utilization efficiency of space target data, thereby improving the ability and level of space system task analysis and performance simulation.

[0037] Aiming at the deficiencies of the prior art, the present invention provides a method for data fusion and data mining of multi-source massi...

Abstract

The invention provides a data fusion and data mining method for multi-type mass spatial target data. According to the method, first, multisource spatial target data is collected, data fusion is performed on the obtained multisource spatial target data, a spatial target information base is formed, a spatial target data management system is constructed according to the spatial target information base, and the spatial target data management system is connected with simulation analysis software; and then data mining is performed on the multisource spatial target data in the spatial target information base, meanwhile, data input is provided for planning simulation of satellite earth observation task scheduling, and planning simulation analysis of satellite earth observation task scheduling is performed to obtain optimized satellite earth observation task scheduling. Through the method, the multisource data fusion technology is utilized to perform collection, sorting and efficient fusion onmultiple types of needed data, data support and decision support can be provided for aerospace system task analysis and efficiency simulation calculation, and the method has high application value.

Description

technical field [0001] The invention relates to the technical field of aerospace system task analysis and computer simulation, in particular to a method for data fusion and data mining of multi-type massive space target data, which provides data support and information support for aerospace system task analysis and system performance simulation. Background technique [0002] With the development of aerospace technology, the number of space targets on orbit has increased sharply. When performing statistical analysis and system performance simulation on space systems, it is necessary to call various information of various space targets, including orbit, payload, communication, status, etc. At present, the number of space targets in orbit is very large, so the amount of data required is also massive. [0003] At present, for various data of space targets in the world, different international organizations only adopt their own statistical methods based on their own consideration...
