摘要博莱内-2002年实验的目的是开发使用雷达体积扫描战略进行雷达降雨估计在法国山区。开发雷达处理系统，被称为TraitriumRegionalises et Adaptatifs de Donnees Radar pour l 'Hydrologie（水文应用的区域化和自适应雷达数据处理），已经建成，并专门制作了几种算法作为该项目的一部分。这些算法包括1）基于非相干雷达反射率Z的脉冲到脉冲变化的杂波识别技术，2）用于确定对流和广泛降雨R与相关的归一化反射率垂直廓线之间的雨分区的耦合过程，和3）用于从高空测量的反射率计算地面反射率的方法。几种雷达处理策略，包括非自适应，时间自适应，和空时自适应的变种，已实施…
Abstract The Bollene-2002 Experiment was aimed at developing the use of a radar volume-scanning strategy for conducting radar rainfall estimations in the mountainous regions of France. A developmental radar processing system, called Traitements Regionalises et Adaptatifs de Donnees Radar pour l’Hydrologie (Regionalized and Adaptive Radar Data Processing for Hydrological Applications), has been built and several algorithms were specifically produced as part of this project. These algorithms include 1) a clutter identification technique based on the pulse-to-pulse variability of reflectivity Z for noncoherent radar, 2) a coupled procedure for determining a rain partition between convective and widespread rainfall R and the associated normalized vertical profiles of reflectivity, and 3) a method for calculating reflectivity at ground level from reflectivities measured aloft. Several radar processing strategies, including nonadaptive, time-adaptive, and space–time-adaptive variants, have been implemented to a...
