Abstract

Due to diverse and extreme weather conditions, the Peruvian population is vulnerable to high-impact natural disasters. A continuous monitoring of all weather conditions is necessary for accurate weather models, forecast, and nowcast along the territory. To cope with this problem, the Jicamarca Radio Observatory (JRO) is developing a low-cost, portable CLear AIr and Rainfall Estimations (CLAIRE) Radar that will provide tropospheric winds, turbulence, and rainfall estimations that will help analyze and quantify meteorological phenomena. CLAIRE consists of four Yagi-Uda antenna phased arrays, one for transmission and three for reception, arranged in a quasimonostatic system. The 445-MHz CLAIRE system is sensitive to both clear-air and precipitation echoes. The aim is to separate the two types of echoes through spectral analysis and process them independently. For the wind and turbulence measurements, Spaced Antenna technique will be applied, while precipitation measurements will be obtained by analyzing the corresponding radar reflectivity factor (Ze).

克莱尔:用于湍流和降水研究的超高频风廓线雷达

由于气候条件多样和极端，秘鲁人口很容易受到高影响自然灾害的影响。为了建立准确的天气模式、预报和临近天气预报，持续监测所有天气情况是必要的。为了解决这个问题，Jicamarca无线电天文台(JRO)正在开发一种低成本、便携式的空气和降雨估计雷达(CLAIRE)，它将提供对流层风、湍流和降雨估计，这将有助于分析和量化气象现象。CLAIRE由四个Yagi-Uda天线相控阵组成，一个用于发射，三个用于接收，排列在一个准稳态系统中。445mhz CLAIRE系统对晴空回波和降水回波都很敏感。目的是通过频谱分析将两类回波分离并进行独立处理。对于风和湍流测量，将采用间隔天线技术，而降水测量将通过分析相应的雷达反射率因子(Ze)来获得。
