Dual linear polarization radar system and measurement method for strong rain

Abstract

The invention discloses a dual linear polarization radar system. The dual linear polarization radar system comprise a data base module, a strong storm preprocessing module, a data matching and identification module, a strong storm processing module, a data correction module and a strong storm early-warning module. Time and space synchronization of a large-scale or specific-region weather system and collaborative observation of a fine structure are achieved by utilizing an efficient communication network application satellite navigation system adaptive to a weather radar network through an application of radar networking. High-definition GIS information and the collaborative observation are combined, quantitative time and space consistency of networking radar observation is achieved, and abilities to monitor and early warn disastrous weather such as strong rain are improved. The invention further provides a corresponding measurement method for the strong rain on a plateau by utilizing a dual linear polarization radar system network.

Description

Technical field: [0001] The invention relates to a dual linear polarization radar system and a method for measuring heavy rainfall on plateaus by using the dual linear polarization radar system network. Background technique: [0002] The Qinghai-Tibet Plateau accounts for about 1 / 4 of my country's land area, with an average altitude of more than 4km. It is the highest plateau with the most complex terrain in the world, and is known as the roof of the world. The unique topographical conditions of the Qinghai-Tibet Plateau make it different from the weather characteristics of plain areas and general mountains. In the 1970s and 1990s, my country organized two large-scale field scientific experiments on the Qinghai-Tibet Plateau, and achieved very important results. The circulation characteristics, weather system, heat source properties, plateau monsoon and South Asian high in the plateau region were studied in depth, and many new facts were revealed, which laid an important fo...

AI Technical Summary

Problems solved by technology

The main performance is that the vertical resolution of the middle and low layers is relatively low. In mountainous areas, especially in mountainous areas, radar stations adopt volume scanning mode, which results in a small monitoring range of the atmospheric boundary layer, blurred distance and velocity, and weak detection of the clear sky atmosphere and the early development of the weather system. There are many problems such as insufficient echo monitoring ability, obvious deviation in precipitation estimation, insufficient networking and coordination ability, etc.
