Problems solved by technology

This method, on the one hand, consumes a lot of computing overhead and increases computing time; on the other hand, it will introduce redundant data to a certain extent, increase the data volume of product data, and bring unnecessary obstacles to applications such as data transmission.
Therefore, the existing radar reflectivity data vertical section method is difficult to apply to real-time 3D weather monitoring business

Abstract

The method for rapidly obtaining three-dimensional vector data of a vertical section plane of radar reflectivity data provided by the present invention comprises the following steps: normalization of radar three-dimensional scanning data; construction of a hexahedral grid of radar data points; construction of a vertical section plane; radar Calculation of the vertical section data of the reflectivity data; the present invention directly processes the data points detected by the radar by normalizing the scanning data of each layer of the radar, constructs a hexahedral grid, and then directly processes the section through the hexahedron, Quickly obtain vertical slices of radar reflectivity data. The whole process reduces the amount of calculation data and avoids redundant data, greatly improves the acquisition efficiency of the vertical section plane of radar reflectivity data, and can be easily applied to real-time 3D weather monitoring business.

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...
