Weather detection method and system based on multi-band weather radar, and storage medium

Abstract

The invention discloses a weather detection method and system based on a multi-band weather radar, and a storage medium. The method comprises the steps of: obtaining radar echo signals of at least two frequency bands, the radar echo signals comprising a differential propagation phase shift rate and an echo intensity value; calculating according to the differential propagation phase shift rates of all the frequency bands to obtain an intensity correction coefficient of each frequency band; and calculating according to the intensity correction coefficient of each frequency band and the echo intensity value to obtain a detection result. According to the method, the radar echo signals of the multiple frequency bands are obtained, the intensity correction coefficient is calculated and determined by adopting the differential propagation phase shift rates in the radar echo signals, the intensity correction coefficient is adopted to correct the intensity value, and the detection results of the multiple frequency bands are obtained. Therefore, joint optimization of detection data of multiple frequency bands is realized, and the data quality of radar detection is improved. Meanwhile, accurate inversion of radar detection echo data is realized, and the accuracy of radar detection is ensured.

Description

technical field [0001] The invention relates to the technical field of weather radar measurement, in particular to a weather detection method, system and storage medium based on a multi-band weather radar. Background technique [0002] More than 50% of the earth's surface is covered by clouds, and clouds play a pivotal role in atmospheric energy distribution, radiation transfer, and especially in the water cycle system. In the earth-atmosphere system, clouds transport heat to the atmosphere in the form of latent heat, and the solid and liquid water contained in them will not only cause natural precipitation, but also have a significant impact on weather and climate, and are also the most important object of artificial weather modification Therefore, the observation and research on the distribution, characteristics and evolution of clouds and rain have become one of the hotspots in atmospheric science research, and are of great significance in the fields of cloud physics rese...
