Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to a layer-by-layer repair method, system and computer storage medium for millimeter-wave radar reflectivity. Background technique [0002] In recent years, local power grid icing incidents have occurred frequently in winter, which will have a serious impact on national production and life. In order to improve the anti-icing capability of the power grid, it is necessary to accurately grasp the micro-meteorological conditions of on-site icing, and carry out environmental monitoring and early warning of icing on transmission lines. [0003] At present, power grid enterprises have deployed a large number of micro-meteorological monitoring devices, but due to the limited monitoring range of the monitoring devices, they can only obtain the meteorological conditions near the monitoring points. If the micro-meteorological monitoring of the entire line section is...
