Development of a New Technology Mobile Doppler Weather Radar Network

9871207Wurman根据MRI计划，主要研究者将升级和改进一个称为车轮上多普勒（DOW）的移动的多普勒雷达系统。 目前的系统提供了关于龙卷风和飓风子结构的独特数据。 预计升级后的系统将提高天线控制系统的可靠性和准确性，并可建造和测试收发分置能力原型。 双基地雷达网络能够使用单个发射机和一个或多个无源远程接收机来测量矢量风场。 由于双基地接收机价格便宜，易于部署，并且不需要大型扫描天线或发射机，因此它们能够使用来自附近发射DOW的信号被部署在感兴趣的天气周围。由于它们能够接近大气现象，道斯通常可以提供比从固定站点雷达获得的高得多的分辨率数据。 预计将从包括龙卷风、飓风、微暴流和地形降水在内的广泛的气象现象中获得独特的数据集。 ***

9871207Wurman Under the MRI Program, the Principal Investigator will upgrade and improve a mobile Doppler radar system known as the Doppler on Wheels (DOW). The current systems have provided unique data on both tornadoes and hurricane substructures. It is anticipated that the upgraded systems will provide better reliability and accuracy of the antenna control system and provide the construction and test of a prototype bistatic capability. Bistatic radar networks are capable of measuring vector wind fields using a single transmitter and one or more passive remotely located receivers. Since bistatic receivers are inexpensive, easy to field, and do not require large scanning antennas or transmitters, they are capable of being deployed en masse surrounding weather of interest, using signals from a nearby transmitting DOW. Due to their ability to be brought close to atmospheric phenomena, the DOWs can generally provide much higher resolution data than can be obtained from fixed site radars. It is anticipated that unique data sets will be forthcoming from a wide range of meteorological phenomena including tornadoes, hurricanes, microbursts, and orographic precipitation. ***
