Abstract

Abstract

A software for analyzing objectively the horizon of Doppler weather radar stations is developed. According to the geographic information of the selected radar station and its periphery, the software can calculate speedily and display automatically the barricaded elevation map as well as the range-azimuth distribution maps for different heights of a single radar station and the composite map for multiple radars under the Mercator or Lambert projection mode. It provides an objective tool to analyze and appraise the possible horizon of Doppler radars, the combined coverage effect of the conjoint radar network and the quantitative application of radar data.
