Congratulations to ARRC Ph.D. student Jose Diaz whose paper, “A Dual-Polarized Stacked Patch Antenna with Wide-Angle and Low Cross-Polarization for Fully Digital Multifunction Phased Array Radars”, won 1st place in the highly competitive student paper competition at the 2016 IEEE Phased Array Conference held recently in Waltham, Massachusetts. Jose works under the supervision of Dr. Jorge Salazar.

The OU School of Meteorology has two tenure-track faculty positions available at the Assistant or Associate Professor level beginning in the academic year 2017-2018. The School is seeking candidates with the ability to establish, lead, and sustain a strong and visible research program. Applicants must also have a commitment to excellence in teaching and mentoring at the undergraduate and graduate levels plus a strong desire to participate in the School, University, and atmospheric science community.

Congratulations to ARRC/ECE faculty member Dr. Caleb Fulton for recently being elevated to Senior Member status in the IEEE. He is a member of the Microwave Theory and Techniques, Antennas and Propagation, and Aerospace and Electronic Systems Societies.

Rockwell Collins is teaming with OU and Stanford University on the next phase of the DARPA Arrays at Commercial Timescales project, which seeks to commoditize digital phased array electronics through commonality amongst different platforms and application spaces. The unique approach of the Rockwell/OU/Stanford team is to combine highly-reconfigurable SiGe RF frontends with low-power ADCs and mid-grade FPGAs to deliver an inherently low-cost and architecturally flexible digital array “common module.” The team demonstrated the first iteration of this module during Phase I last year, with Stanford providing the ADCs and OU providing the core digital beamforming and calibration functionality on the FPGA. In this 15-month Phase II effort, the team will work even more closely together to upgrade all of the constituent common module components, providing advanced digital beamforming functionality that is beyond the state-of-the-art. Other performers on DARPA ACT Phase II include Boeing, with an entirely CMOS-based module, and Northrup Grumman, who are building their modules with the latest (and therefore most expensive) semiconductor technology processes.

ARRC/SoM faculty member Dr. Guifu Zhang's book "Weather Radar Polarimetry" was released August 1, 2016 by CRC Press. The book presents the fundamentals of polarimetric radar remote sensing through understanding wave scattering and propagation in geophysical media filled with hydrometers and other objects. The text characterizes the physical, statistical, and electromagnetic properties of hydrometers and establishes the relations between radar observables and physical state parameters. It introduces advanced remote sensing techniques (such as polarimetric phased array radar) and retrieval methods for physical parameters. The book also illustrates applications of polarimetric radar measurements in hydrometer classification, particle size distribution retrievals, microphysical parameterization, and weather quantification and forecast.

Editorial Reviews: "This text will be invaluable to students and researchers who are applying cutting-edge radar sensing technology and numerical forecast techniques to improve forecasts of precipitation and severe weather."...."This is a unified treatment of "weather radar" and "polarimetric radar." These two areas are closely related, but often treated separately. "...."This book perfectly fits the needs of the radar and meteorological communities which have to be better educated about the advantages and potential of this new technology."...."Dr. Zhang's wide range of expertise in formulating and developing focused research to solve cutting edge problems in radar meteorology has made this book attractive to academic, research, and operational communities. The author interweaves science and engineering aspects of weather radar polrimetry seamlessly. This approach has made the book valuable course material as well as a great resource for practicing radar meteorologists."
