Method for comparing volume scanning data of weather radars

Abstract

The invention discloses a method for comparing volume scanning data of weather radars. The method belongs to the technical field of weather radar data processing, and comprises the steps of: step 1, acquiring volume scanning data of multiple weather radars, wherein the volume scanning data comprises detection data respectively detected by a plurality of detection points of the multiple weather radars, acquiring a position of each detection point, and putting the detection data corresponding to the detection points into a preset three-dimensional spatial position form according to the positionsof the detection points; step 2, performing data smoothing arrangement on each piece of the detection data put into the three-dimensional spatial position form respectively to obtain smooth data corresponding to each piece of the detection data; step 3, and selecting the multiple weather radars to be compared, and comparing the smooth data of the multiple weather radars at the same position in the three-dimensional spatial position form. The method avoids the mismatching problem of data among different radars, and solves the problem that compared reference points cannot be unified due to thedifferent positions of the weather radars, thereby improving the comparison efficiency.

Description

technical field [0001] The invention relates to the technical field of weather radar data processing, in particular to a method for comparing volume scan data of weather radar. Background technique [0002] Weather radar is the most common radar detection equipment in modern meteorological detection instruments, and it is the main tool for monitoring and early warning of strong convective weather. The commonly used working mode of weather radar is body scanning, that is, by adjusting the pitch angle, it scans the sky at different altitudes in a circle , the space meteorological information can be obtained after combining multiple elevation angle scans. In the weather radar debugging stage, the radar debugging efficiency can be effectively improved by comparing the data of multiple weather radars. [0003] However, due to reasons such as inter-radar interference or site restrictions, each radar cannot be located at the same position. Different radars are located in different...

Problems solved by technology

[0003] However, due to reasons such as inter-radar interference or site restrictions, each radar cannot be located at the same position. Different radars are located in different positions. The detected data will be centered on the position of the radar. as a reference point

When comparing multiple radar data, if the data reference points are different, it is impossible to confirm which data detects the same location in space, so different detection locations will cause problems in the correspondence between radar volume scan data
