"New Trends in Antenna Array Architectures for Multifunction Phased Radar System"
In the past twelve years there has been an exponential increase in the demand for use of RF electronics for wireless technology which has been instrumental in stimulating unprecedented growth in other applications including imaging, remote sensing, and radar detection. The need to develop new radiating antennas and microwave/millimiter-wave components for frequency diversity, small size, low-power consumption, and low-cost inspired creative designs to address the new challenges. The remarkable speed of RF allows engineers to interactively generate and design complicated structures and enables them to quickly discern the necessary manufacturing processes for prototyping and development. This presentation will provide an overview of the current state of the art in addition to trends in the technology of antennas and sensors, including millimiter-wave designs for phased-array antennas and the requirements for radar and communication systems for civil and military applications. An overview of current and new trends in phased-array architectures and technology for multifunction radar systems for civil and military applications, focusing on a critical evaluation of the performance of ultra-low cross polarization phased array antenna systems will be presented.
Jorge L. Salazar-Cerreno received a B.S. in ECE from the University Antenor Orrego, Trujillo, Peru, M.S. degree in ECE from the University of Puerto Rico, Mayaguez (UPRM). 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 (CASA). After graduation, Dr. Salazar-Cerreno was awarded a prestigious National Center for Atmospheric Research (NCAR) Advanced Study Program (ASP) postdoctoral fellowship. At NCAR, he worked at the Earth Observing Laboratory (EOL) 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 2014, 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/Rx modules; radome EM modeling; RF and hardware development for characterizing and calibrating APAA and millimiter-waver antennas for automobile and communication systems. His research team (PAARD) is collaborating with the U.S. National Oceanic and Atmospheric Administration (NOAA), NASA-JPL, the U.S. Navy Research Lab (NRL), the U.S. Army Research Lab (ARL), the U.S. Air Force Research Lab (AFRL), 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 (TGARS), The Radio Science Journal, and John Wiley and Sons (https://www.ou-arrc-paard.com/).
