Abstract

The invention provides a satellite data fusion method and device and electronic equipment, and the method comprises the steps: carrying out the data conversion of the swath grid data of a plurality ofsatellites, so as to obtain the first longitude and latitude grid data of the plurality of satellites; performing error analysis on the first longitude and latitude grid data of the plurality of satellites, and endowing each piece of first longitude and latitude grid data with a weight to obtain second longitude and latitude grid data of the plurality of satellites; and performing variational analysis on the second longitude and latitude grid data of the plurality of satellites to obtain satellite fusion data.

Description

technical field [0001] The present application relates to the technical field of satellite data processing, in particular, to a satellite data fusion method, device and electronic equipment. Background technique [0002] Sea surface wind field data observed by satellite microwave remote sensing instruments are playing an increasingly important role in ocean and atmospheric operational monitoring and forecasting. However, the observation data of a single satellite remote sensing instrument within a day is limited. For example, usually only two observations can be made on the same area, which cannot be directly applied to operational systems that require high temporal and spatial resolution of data. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present application is to provide a satellite data fusion method, device and electronic equipment. It can reduce the single deficiency of satellite data in the existing processing method. ...
