Abstract

The invention provides a method for quickly acquiring three-dimensional vector data of a vertical cutting plane of radar reflectivity data. The method comprises the following steps of: normalizing radar three-dimensional scan data; constructing a hexahedron mesh of radar data points; constructing a vertical cutting plane; and calculating vertical cutting plane data of the radar reflectivity data.The invention normalizes scanning data of each layer of the radar, directly processes the data points detected by the radar to construct the hexahedral mesh, and then quickly acquires the vertical cutting plane of the radar reflectivity data through a cutting process for the hexahedron. The whole process reduces the amount of calculation data and avoids redundant data, greatly improves acquisitionefficiency of the vertical cutting plane of the radar reflectivity data, and can be conveniently applied in the real-time three-dimensional weather monitoring service.

Description

Technical field: [0001] The invention relates to a method for quickly acquiring the vertical section plane of radar reflectivity data. Background technique: [0002] The vertical section plane of radar reflectivity data can express the internal data characteristics of the rainfall cloud very intuitively, which is of great significance for the discrimination of rainfall weather. At present, the acquisition of the vertical section plane of the conventional radar reflectivity data is based on a three-dimensional regular grid. In this process, the arrangement of the three-dimensional regular grid is very different from the scanning method of the radar volume. Therefore, it is necessary to perform interpolation calculations on the existing radar detection data of each layer to obtain the corresponding position of each three-dimensional regular small grid. Data value, and then calculate the section data on the basis of this. This method, on the one hand, consumes a lot of comput...
