MRI: Development of C-band Mobile Polarimetric Imaging Radar

这一重大研究仪器奖是为了表彰极化先进成像雷达(PATE)的发展。Pair将是一个车载天气雷达系统，能够以极快的速度更新，并能够观察雨滴和雪花的高级特征。该雷达将是一个相控阵系统，传统上是军方使用的，但现在天气雷达界正在获得更广泛的使用。该雷达将把当前移动雷达系统的一些最好的属性，如非常快的扫描、高分辨率和双极化等结合在一个系统中。雷达的用途将包括研究龙卷风、超级单体雷暴、闪电、飓风、将雷达数据同化到计算机模型中，甚至雷达空气生态学，这是对鸟类和昆虫在空中移动的研究。该项目对社会的更广泛影响将通过增加对恶劣天气的了解来实现，这将导致更好的警告，以提醒公众危险条件。学生将获得实际工程经验，以配合气象科学的背景。将通过与波多黎各大学、马亚圭兹大学和俄亥俄州立大学印第安人科学与工程学会(AISES)分会的伙伴关系确保代表人数不足的群体的参与。PAIR将是一个相控阵雷达系统，能够在方位上进行电子扫描，在垂直方向上采用泛光灯模式，其中将发射20°扇形波束。Pair试图通过提供最高的扇区体积更新率、同时的双极化估计和当前移动雷达的最高本征距离分辨率来弥合现有系统之间的差距，同时保持1.5°的有效波束宽度。该雷达将用于上述科学课题，以及天气雷达技术和极化相控阵系统等更基本的课题。

This Major Research Instrumentation award is for the development of the Polarimetric Advanced Imaging Radar (PAIR). PAIR will be a truck-mounted weather radar system capable of extremely fast updates and the ability to observe advanced characteristics of raindrops and snowflakes. The radar will be a phased-array system, which has traditionally been used by the military but is now gaining broader usage by the weather radar community. The radar will combine some of the best attributes of current mobile radar systems, such as very fast scanning, high-resolution, and dual-polarimetry into one system. Radar uses will include studies of tornadoes, supercell thunderstorms, lightning, hurricanes, radar data assimilation into computer models, and even radar aeroecology, which is the study of the movement of birds and insects through the air. The broader impacts of the project on society will come through increased knowledge of severe weather which will result in better warnings to alert the public of hazardous conditions. Students will gain hands-on engineering experience to go along with a background in meteorological science. The participation of underrepresented groups will be assured through partnerships with the University of Puerto Rico, Mayaguez and the OU American Indians in Science & Engineering Society (AISES) chapter.PAIR will be a phased-array radar system capable of electronic scanning in the azimuth and a floodlight mode in the vertical where a 20° fan beam would be transmitted. PAIR seeks to bridge the gap between existing systems by providing the highest sector volume update rate, simultaneous dual-polarimetric estimates, and the highest native range resolution of current mobile radars, while maintaining an effective beamwidth of 1.5°. The radar will be used for the scientific topics mentioned above as well as more fundamental topics in weather radar technology and polarimetric phased array systems.
