Abstract

The invention provides a regional meteorological radar network data fusion method and device. According to the method, three-dimensional meteorological data of all the radars in the regional meteorological radar network are spliced in a unified Cartesian coordinate system; for each grid cell in multiple radar overlapped coverage areas, a weight value of each radar is calculated, and the optimal three-dimensional meteorological data of each grid cell in the multiple radar overlapped coverage areas is determined according to the weight value of each radar and the three-dimensional meteorologicaldata of each radar. The method is advantaged in that the meteorological data of the overlapped grid cells are processed according to the radar weight values related to distance and resolution parameters, for the isomorphic radar network as well as the heterogeneous radar network, not only can fine-scale meteorological data characteristics be kept to the maximum degree, but also the continuous space radar mosaic result can be acquired, and the meteorological radar mosaic result is made to be more accurate.

Description

technical field [0001] The invention relates to the technical field of meteorological observation, in particular to a data fusion method and device for a regional meteorological radar network. Background technique [0002] The regional meteorological radar network is composed of multiple meteorological radars distributed in space. By combining, correlating and organizing the meteorological data collected by each radar in the regional meteorological radar network, the meteorological information in a region can be obtained. The meteorological data collected by the radar is in the unit of grid unit, and the coverage areas of different radars partially overlap to ensure the complete meteorological information in an area. Therefore, how to accurately calculate the meteorological data value of the overlapping grid unit, It will have an important impact on the accuracy of the obtained meteorological information. [0003] In the prior art, common methods for calculating meteorologi...
