Abstract

The invention provides a multi-satellite cooperative detection method and device in a space information network and relates to the technical field of satellite detection. The method comprises the steps of a first obtaining step, obtaining detection data detected by a current satellite at a current moment; a deduction step, deducing the environment state of a detection target according to the detection data to obtain a first deduction result; a second obtaining step, obtaining a second deduction result of a target satellite; a fusing determination step, fusing the first deduction result and the second deduction result to obtain a fusion result; and repeatedly carrying out iterative processing on the first obtaining step, the deduction step, the second obtaining step and the fusion determination step until the iteration stop condition is met and taking the environment state corresponding to a target fusion result in the fusion results when the iteration stop condition is met as the real environment state of the detection target at the current moment. According to the multi-satellite cooperative detection method and device, the technical problem that the detection efficiency and the detection accuracy are relatively poor when the environment state is detected by adopting single satellite in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of satellite detection, in particular to a multi-satellite coordinated detection method and device in a space information network. Background technique [0002] In the space network, satellites are often used for meteorological, oceanographic, geological, disaster, space and other environmental detection tasks, and their detection data are used in weather forecasting, geological exploration, disaster early warning and other fields. However, due to the limited detection capability of a single satellite, for example, the limited types of parameters that can be detected by a single satellite, the presence of noise in the detection results, and the inability to effectively detect due to location constraints, the above defects will sometimes make it difficult for a single satellite to perform well. complete the detection task. [0003] For the above problems, no effective solution has been proposed yet. Conten...
