Distributed multi-source information fusion system suitable for multi-satellite formation

Abstract

The invention provides a distributed multi-source information fusion system and method suitable for multi-satellite formation. The system comprises a module M1 which takes charge of completing the target detection and feature extraction of single-source information through a formation member star information processing unit as a local information processing node; and a module M2 which is used forsending the target detection and feature extraction of the single-source information to a central satellite information fusion unit by each member satellite to perform multi-source information fusionprocessing, completing the calculation load balance of each member satellite and realizing the cooperative processing in a spatial distributed environment. The system can make full use of the advantage that each member satellite of a multi-satellite system is configured with different types of sensors, adopts a multi-source data information fusion means to realize multi-source data on-orbit comprehensive processing, has the characteristics of high processing real-time performance, high autonomy degree, rich result information and the like, and is especially suitable for multi-source information fusion under multi-satellite formation.

Description

technical field [0001] The invention relates to aerospace vehicles, in particular to a distributed multi-source information fusion system suitable for multi-satellite formations. Background technique [0002] Multi-source information fusion, also known as multi-sensor information fusion, was proposed in the 1970s. Military applications are the cause of the birth of this technology. Multi-source information fusion mainly refers to the use of multiple information sources such as sensors, databases, knowledge bases, etc. To obtain information, filter, correlate, and integrate to form a representation architecture, which is suitable for obtaining relevant decisions, interpreting information to achieve target identification, system control, etc. In recent years, multi-sensor information fusion technology has received extensive attention in both military and civilian fields. This technology is being widely used in automatic target recognition, automatic aircraft navigation, roboti...
