We are excited to announce that the ARRC is expanding our professional team. Multiple positions are available for each of the job postings in the links below. Please help in our expansion process.
OU Regents recently included the Radar Innovations Lab as part of their tour of the Research Campus. Pictured with ARRC Executive Director Bob Palmer (center) are (l. to r.) Tim Rhodes, Executive Secretary of the Board of Regents, Regents Rick Braught and Robert Ross, and John Antonio, Sr. Associate VP for Research and Partnerships.
Congratulations to ARRC/ECE PhD student Cesar Salazar for obtaining the best student paper award at the 11th European Conference on Radar in Meteorology and Hydrology, held in Locarno, Switzerland from 8/29 to 9/2. He is being advised by Drs. Palmer and Cheong, and is currently in his last semester of the PhD program.
Cesar’s paper titled, “Progressive Pulse Compression: A Promising Solution to the Blind Range Challenge for Solid-State Weather Radar”, was presented in the Radar Signal and Doppler Processing session. The paper discussed the novel progressive pulse compression technique (PPC), which mitigates the blind range that typically obscures pulse-compression data near the radar. The presentation was focused on applications of PPC to a variety of meteorological events (convective/stratiform precipitation systems) and using different scanning modes (PPI, RHI, STSR and ATSR) to collect the data. Cesar also briefly discussed the enhanced version “PPC ” which further reduces range-sidelobe contamination within the recovered blind range. The key takeaway was that PPC can retrieve polarimetric measurements at ranges close to the radar, even with long pulse compression waveforms, without impacting data quality. Congratulations, Cesar!
Shane Flandermeyer is an M.S. student in the School of Electrical and Computer Engineering, advised by Dr. Justin Metcalf.
How long have you been a part of the ARRC:
"I joined the ARRC as an undergraduate in Fall 2018 through the Honors college FYRE program, where I worked with Dr. Metcalf on developing open-source software for doing radar with software-defined radio (SDR) systems. I completed my B.S. in electrical engineering in the Spring, and I am just beginning to work on my master’s thesis this semester."
Scholarships/journal awards/publications etc. that you have received:
• National Science Foundation Graduate Research Fellowship Program (GRFP) award
• Astronaut Scholarship
• Outstanding Senior in electrical engineering
• S. Flandermeyer, R. Mattingly and J. Metcalf, “gr-plasma: A New GNU Radio-based Tool for Software-defined Radar”, Proceedings of the GNU Radio Conference, 2022 (Accepted)
"For my thesis, I plan to examine the use of various reinforcement learning methods for performing radar resource management problems such as task scheduling, beam positioning, and parameter selection. I also maintain a GNU Radio module for collecting and processing radar data from SDRs in real time."
What do you like to do in your free time:
"In my free time, I enjoy lifting weights, practicing judo, and playing basketball."
Plans for after graduating:
"After completing my M.S., I plan to stay at the ARRC to pursue my Ph.D. and to continue researching the applications of machine learning to radar problems."
Oklahoma Native and Deputy Chief of Naval Operations for Information Warfare, Vice Admiral Jeffrey Trussler, recently visited the University of Oklahoma and toured the Radar Innovations Lab with Bob Palmer, executive director of the Advanced Radar Research Center and Gene Kirkland, executive director of the Oklahoma Aerospace and Defense Institute.
"What if you could detect a tornado with greater confidence minutes before the funnel reached the ground, posed a grave danger to life, and tracked its path along the ground with much greater accuracy?
Today, meteorologists, data scientists, and engineers at the University of Oklahoma’s Advanced Radar Research Center (ARRC), in collaboration with Analog Devices Inc. (ADI), are designing, building, testing, and fielding a next-generation, all-digital polarimetric phased array radar system. The breakthrough innovation funded by NOAA’s National Severe Storms Laboratory (NSSL) will allow for real-time monitoring, improved forecasting, and the earlier detection of severe weather than anything that has come before."

We are hosting a student-led virtual workshop to plan a field experiment with the NSF CIF RaXPol mobile radar in Florida on August 24 from 2-5 CT! Students will work together to determine the science objectives and radar scanning strategies. You can register for the workshop here.
In September, students can virtually participate in the RaXPol experiment. We will have a live camera view to see RaXPol in action, as well as a link to our live data display! Short courses on radar and thunderstorms will also be offered.
The ARRC's Executive Director, Bob Palmer, has been named Education Innovator of the Year by 405 Business Magazine.
Dr. Palmer said, "There is no other organization like the ARRC in the country. We are academic, but have a start-up feel and culture. Our members (faculty, staff, and students) are the best in the world, and we have put OU on the map regarding innovations in radar. Customers now come to us for solutions."

Congratulations to SoM/ARRC Postdoctoral Fellow Yagmur Derin for being awarded the International Precipitation Working Group Early Career Scientist Award - First Prize for outstanding presentation/poster 2022!
IPWG is part of the World Meteorological Organization (WMO) and focuses the scientific community on operational and research satellite-based quantitative precipitation measurement. Yagmur presented on the challenging topic of quantitative precipitation estimation from satellites in complex terrain. Precipitation estimation in mountainous regions is uncertain because interacting processes between the atmosphere and topography are difficult to observe. Yagmur uses the U.S. ground radar network and environmental conditions from numerical models to capture the conditions where precipitation estimation from space is challenged. Her research benefits NASA's Global Precipitation Measurement (GPM) mission. The GPM mission involves an international network of satellites that provides global observations of rain and snow to advance our understanding of Earth's water and energy cycle, improve forecasting of extreme events, and provide accurate and timely information to directly benefit society. Yagmur is supervised by Dr. Pierre Kirstetter.
