CAREER: Bistatic and Mobile Multiple-Doppler Technique Development and Educational Laboratory

9703032 Wurman根据教师早期职业发展计划（Career），首席研究员将从事与多普勒雷达在气象研究中的两种新的创新用途相关的研究和教育活动。固定站点单台或多普勒雷达在气象研究中已经应用多年，在某些方面已经非常成熟。由于技术的进步，研究多普勒雷达已经发展到可以安装在移动地面和机载平台上的状态。在其他支持下，首席研究员已经开始开发两种移动式地面多普勒雷达系统，它们比固定站点具有许多优势。其中最主要的是能够获得更多的数据集，并以更高的空间分辨率获得数据。然而，伴随着这些优势，在数据分析/综合方面也出现了一些特殊的问题。例如，与固定雷达站点相比，较高的俯仰角可能会导致一些潜在的问题。此外，在移动中收集数据的可能性也为开发最佳实验设计和数据分析提供了特殊的挑战。研究的第二个领域，首席研究员将追求的是使用双基地多普勒网络。这是一个由一个发射雷达和许多分布式接收器组成的网络。这是一项非常新的技术，在许多其他技术中，它的优势是提供相对便宜的大面积风场地图。首席研究员将继续研究这种网络的最佳设计和利用。根据该CAREER奖的教育部分，首席研究员将把移动多普勒和双基地网络纳入研究生课程，并为学生举办夏季研讨会。这将使学生参与最新气象雷达技术发展的前沿研究。* * *

9703032 Wurman Under the Faculty Early Career Development Program (CAREER), the Principal Investigator will pursue research and educational activities associated with two new and innovative uses of Doppler radars for meteorological research. Single or multiple Doppler radars at fixed sites have been utilized for many years in meteorological research and some aspects of their use are very mature. Due to technological advances, research Doppler radars have evolved to the state where they can be mounted in mobile ground-based and airborne platforms. Under other support, the Principal Investigator has begun to develop two mobile ground-based Doppler radar systems which provide many advantages over fixed sites. Primary among these are the ability to acquire many more data sets and to obtain data at much higher spatial resolution. Along with these advantages, however, also comes special problems in data analysis/synthesis. For example, higher elevation angles than normally encountered with fixed radar sites may cause some potential problems. Additionally, the possibility of collecting data while moving also provides special challenges in developing optimal experimental designs and in analysis of data. The second area of research the Principal Investigator will pursue is the use of bistatic multiple Doppler networks. This is a network consisting of one transmitting radar with a network of many, distributed receivers. This is very new technology that has the advantage, among many others, of providing relatively inexpensive mapping of wind fields over large areas. The Principal Investigator will continue research into the best design and utilization of such networks. Under the educational component of this CAREER award, the Principal Investigator will incorporate the mobile Dopplers and bistatic networks into graduate courses as well as host Summer workshops for students. This will integrate students into research that is at the very cutting e dge of development of new meteorological radar technologies. ***
