Problems solved by technology

[0005] The paper "Testing and Evaluation of Multi-sensor Information Fusion Performance" 1000-3428 (2003) 10-0084-02 proposed a method of testing and evaluating the performance of multi-sensor information fusion through software testing. It is a quantitative evaluation method to evaluate the performance of multi-sensor information fusion, but this method cannot be applied to the ground physical test of multi-satellite distributed fusion system
[0006] The paper "Research on C-3I Information Fusion Test and Evaluation System" 1000-7024 (2008) 05-1135-03, gives the general theory and method of information fusion system evaluation, and gives a fusion test based on soft bus structure evaluation system, but this system cannot be used for the purposes described in this patent

Abstract

The invention provides a multi-satellite joint test method and system for a multi-satellite distributed information fusion system, and the method comprises the steps: S1, selecting a visible light image of a preset scene, and transmitting a load performance parameter and a task parameter to each member satellite; the member satellites generate effective load simulation data of the satellites by combining the visible light images of the same scene according to the load performance parameters and the task parameters with preset auxiliary information; s2, each member satellite is powered up, and effective load simulation data of each satellite is sent to a corresponding on-satellite image processing unit of each member satellite through a ground simulation source to be processed, so that target detection and recognition are completed; s3, the central satellite is powered up, and the member satellites send processing results of target detection and recognition on the member satellites to a central satellite information fusion unit through inter-satellite high-speed links for multi-source information fusion processing; and S4, after multi-source information fusion processing is completed, a processing result is sent to the ground through an over-the-ground data transmission link for interpretation and evaluation.

Description

technical field [0001] The invention relates to a multi-satellite distributed information fusion system, in particular to a multi-satellite joint test method and system of a multi-satellite distributed information fusion system, which can be applied to the ground test of the system interface, work flow and main functions. Background technique [0002] Multi-source information fusion, also known as multi-sensor information fusion, was proposed in the 1970s, and military applications are the reason why this technology was proposed. Multi-source information fusion obtains information cooperatively through multiple sensors of the same type or different types, and filters, correlates, and fuses the obtained information, which can effectively estimate and judge the actual situation of the target, which is more accurate and accurate than the information obtained by a single sensor. reliable. In recent years, multi-sensor information fusion technology has received extensive attenti...
