Volume scanning mode calculation method and application based on networking weather radar coverage area

Abstract

The invention discloses a volume scanning mode calculation method and application based on a networking weather radar coverage area, and relates to the technical field of networking radars. The methodcomprises the following steps: constructing an initial weather radar network three-dimensional grid point field based on networking weather radar data in a target area, and identifying grid point coverage information in the three-dimensional grid point field; determining a blind area, and identifying the boundary of the blind area; collecting data of radars to be added, for each radar to be added, configuring volume scanning mode parameters of the radar based on blind area recognition, and calculating the minimum azimuth angle, the maximum azimuth angle and the scanning range between set heights and then fusing to obtain final sector scanning parameters. According to the invention, the blind area can be identified based on the radar coverage area information, the body scanning mode parameters of the weather radars to be added are adaptively configured in combination with the position parameters and other information of the weather radars, and a decision basis is provided for a user tointroduce the radars to perform blind compensation data fusion, perform radar collaborative networking layout and the like.

Description

technical field [0001] The invention relates to the technical field of networked radars, in particular to a calculation method and application of volume scan mode based on the coverage area of ​​networked weather radars. Background technique [0002] Weather radar plays a very important role in the modern comprehensive meteorological observation system. It has a good ability to monitor large and medium-scale weather systems and provides intuitive data for short-term weather forecasts. With the continuous improvement of weather radar performance, the number of radar units erected gradually increased, forming a weather radar network. [0003] The geometric structure and information fusion of networked weather radars have the flexibility to adapt to various weather radar scenarios and applications, and become one of the research hotspots in the field of weather radars today. Networked weather radar can increase the dimension and confidence of measurement, improve the fault tol...
