Abstract
In the past twelve years, remarkable grow of new microwave devices due to the exponential increase in the demand wireless communications. Decades ago, phased array antennas technology, was mainly used for military applications due to the high cost. Today phased array antennas are affordable, reliable and tort-effective. Fast scanning update (less than 20 seconds) enables fad temporal resolution, a key feature for weather observation. Phased arrays also enable reconfigurable beam shape than enables dynamic search of weather target. This presentation will provide an overview of the current date of the art phased array weather radars, design consideration, challenges and limitations. In addition, a discussion of new trends in the technology of antennas, T/R modules, including millimeter-wave designs trade-offs for phased-array antennas for weather and communication systems for civil applications.

About the speaker: Dr. Jorge L. Salazar-Cerreno received a B.S. In ECE from the University Adenor Orrego, Trujillo, Peru, M.S. degree in ECE from the University of Puerto Rico, Mayaguez 91P111M). In 2011, he received his Ph.D. degree in ECE from the University of Massachusetts, Amherst. His Ph.D. research focused on development of low-cost dual-polarized active phased array antennas (APAA) for the Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere KASA). After graduation, Dr. Salazar-Cerreno was awarded a prestigious National Center for Atmospheric Research HICAR) Advanced Study Program (ASP) postdoctoral fellowship. At NCAR, he worked at the Earth Observing Laboratory MOM division developing airborne technology for two-dimensional, electronically scanned, dual-pol phased array radars for atmospheric research. This is a critical tool for studying weather and related hazards, especially for retrieving dynamic and microphysical characteristics of clouds and precipitation over rugged terrain or the open ocean, where other radar systems can have major limitations. In July 2019, he joined the Advanced Radar Research Center (ARRC) at The University of Oklahoma as a research scientist, and became an assistant professor at the School of Electrical and Computer Engineering in August 2015. His research interests include high-performance, broadband antennas for dual-polarized phased array radar applications; array antenna architecture for reconfigurable radar systems; APAA;Tx/Thr modules; radome EM modeling; RF and hardware development for characterizing and calibrating APAA and millimeter-waver antennas for automobile and communication systems. His research team (PAARD) is collaborating with the U.S. National Oceanic and Atmospheric Administration (NOAA), NASA-1PL, The U.S. Navy Research Lab HIRL),The U.S. Army Research Lab (ARO, the U.S. Air force Research Lab (AFRO, and NCAR. In 2019, Dr. Salazar was awarded the prestigious William H. Barkow Presidential Professorship from The University of Oklahoma. Presidential Professors inspire and mentor their undergraduate and graduate students in research and creative scholarly activity within their discipline, and exemplify professional scholarship through their endeavors in teaching, research, and public outreach. Dr. Salazar is a senior member of the IEEE and currently serves as a reviewer for IEEE Transactions on Antennas and Propagation (TAP), IET Microwaves, Antennas and Propagation (IET), The Journal of Atmospheric and Oceanic Technology (JTECH), IEEE Transactions on Geoscience and Remote Sensing (MARS), The Radio Science Journal, and John Wiley and Sons Ihttps://wwwou-arropaard.comrt.
