气象雷达新技术及其在防灾减灾中的应用

New Weather Radar Technology and Its Application in Disaster Prevention and Reduction

新型气象雷达在国外越来越多地应用于大型外场试验和业务探测网中,我国也将在灾害性天气监测网中引入新型气象雷达。简要介绍了气象雷达的发展历史和国内外发展现状,阐述了气象雷达探测新技术,包括双线偏振雷达、双(多)基地雷达、相控阵天气雷达技术、激光天气雷达技术、风廓线雷达等的探测原理及其在气象中的应用,这对于我国新型雷达的应用和根据实际需求选择雷达类型等具有一定的指导和借鉴意义。

New kinds of weather radar have been widely used in large scale of science experiment and operation abroad and they will be introduced in operational detective net in China in future（ The history and present condition of the development of weather radar technology at home and abroad are presented. The paper elaborates the detective technology, detecting principle and potential application of new kinds of weather radar, including the dual linear polarization Doppler radar, bistatic （multistatic） weather radar, phased radar, laser radar and wind profile radar. The developing status of weather radar was present simply in this paper. It will be useful for application of new kinds of radar and selecting radar based on practical needs in our country.
