Development of a New Technology Mobile Doppler Weather Radar Network

根据核磁共振计划，首席调查员将升级和改进一种被称为轮上多普勒(Dow)的移动多普勒雷达系统。目前的系统提供了关于龙卷风和飓风亚结构的独特数据。预计升级后的系统将为天线控制系统提供更好的可靠性和准确性，并提供原型双基地能力的建造和测试。双基地雷达网络能够使用单个发射器和一个或多个无源远程接收器来测量矢量风场。由于双基地接收器价格低廉，易于现场使用，并且不需要大型扫描天线或发射器，因此它们能够使用来自附近发射道琼斯的信号，在感兴趣的天气周围集体部署。由于它们能够接近大气现象，DOW通常可以提供比固定地点雷达获得的分辨率高得多的数据。预计将从包括龙卷风、飓风、微暴发和地形降水在内的各种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. ***
