Metawave PAARD/ARRC join press releases
OU Radar Team Helping Develop Radar to Help Autonomous Vehicles.
"...In the heart of any beam-steering radio or radar is its automated phase and amplitude calibration system to precisely aim the main beam at specific angles while suppressing interference from side lobes in all operating conditions. At 77GHz where wavelengths are around 3.8mm such calibrations is extremely challenging.
So, on 2018 Christmas Eve I contacted Rodrigo M Lebrón (3ed from the right in last row) via LinkedIn who introduced me to Robert Palmer and Jorge Luis Salazar-Cerreno (on my left) and within few months together with Metawave Corporation team the first high-frequency novel scanner was built, tested, and successfully demonstrated using our 77GHz phase controllers and steerable active antennas. This is startups perseverance and leading professors commitment to mm-wave success. From the bottom of my heart, thank you Jorge Luis Salazar-Cerreno and Shoaib Shafi for perfect collaboration and to our brilliant antenna team Safa Salman Taha Yekan Souren S. and RFIC team Raul Alidio Narek Rostomyan, Ph.D. and Lani Bui .. on to demonstrating the first 77GHz analog radar..." by Maha Acour CEO of Metawave Corporation
PAARD and Metawave in the news!!!
OU Radar Team Helping Develop Radar to Help Autonomous Vehicles.
A University of Oklahoma Advanced Radar Research Center team (PAARD) is collaborating with Metawave, a California company, to develop a newly-designed radar that has the potential to serve as one of the most important sensors in the future of the automotive industry. The OU team assisted with the automation of the calibration system used to electronically steer antennas when making critical driving decisions quickly, safely and smoothly.
“Working with Metawave at these high-frequency bands has been a rewarding experience for our team and has benefitted our program, considering our leadership role in phased array radar calibration,” said Robert Palmer, executive director of the Advanced Radar Research Center. “This type of partnership is important, especially when delivering such cutting-edge technology platforms. Together, we are rethinking how a newly- designed radar can truly serve as one of the most important sensors in the future of the automotive industry,” said Palmer.
Metawave Corporation successfully demonstrated the world’s first automated 77 GHz electronically steerable antenna calibration system for realizing dependable and repeatable beamsteering. “This advanced steering will soon play a significant role for automakers wanting to achieve higher safety standards at low cost and power consumption,” said Metawave Chief Operating Officer and founder Maha Achour. “Metawave is delivering a new kind of automotive radar, one that balances complexity between digital and analog.”
The challenges of this project required an uncommon skill set and experience in active phased array antennas. Jorge Salazar, project team leader and professor in the Gallogly College of Engineering, assembled a diverse team of experts in radar design and calibration to enable the acceleration of this project. ARRC contributors for this project were Rodrigo Lebron, Zeeshan Qamar, Kevin Constien, Thomas Brachtenbach and Jonathan Christian.
“Working with antenna designs for very high frequencies is challenging, especially when the concept involves a radar designed to save lives by improving automobile safety,” said Salazar.
A novel millimeter RF scanner was designed, implemented, validated, and tested on an accelerated path to full demonstration. The customized RF scanner enables testing and calibrating an active array in near-field and far-field operation modes.

Predicting Hope
By Jenna Smith
It was the worst rain in decades, delivering more than 10 times the rainfall than normal. The catastrophic rains wreaked havoc and took homes and lives in Jorge Salazar-Cerreno’s native country of Peru.
Salazar-Cerreno, an assistant professor at the School of Electrical and Computer Engineering and member of the Advanced Radar Research Center, was heartbroken by the devastation. All he could think about was his family and friends back home who were either homeless or grieving their loved ones. The unusually powerful, heavy rains driven by an El Niño flooded Peru along the Pacific coast, leaving more than 90 people dead and 700,000 homeless and wreaked havoc on the country’s infrastructure. The destruction was exacerbated by flashfloods and mudslides... click below to read the full article.

A novel mm-Wave RF Scanner
PAARD Test & Calibration team (Rodrigo, Zeeshan, John, Chris, Thom and Kevin) have developed a state of the art 9-axis RF mmWave scanner for active array radar system. The fully automated mmWave RF scanner that enables the testing and characterization of antennas and active arrays in addition to electromagnetic tests of materials was developed at the ARRC. This unique instrument provides four modes of operation, a direct far-field (FF) antenna test, an indirect far-field test based on a near-field planar raster scan, an active array characterization and calibration, and electromagnetic material characterization. The design project started in Jan. 19, 2019 and system was validated in March 4th, 2019

The Advanced Radar Research Center (ARRC) at The University of Oklahoma developed an innovated technique for in-situ antenna characterization, and radar calibration using an Unmanned Aircraft System (UAS). A large multirotor platform was developed for long endurance (∼ 30 minutes), high position precision (< 2 cm), and high stability was integrated with high a precision 3-axis gimbal that holds an antenna array, pulse generator transmitter. The platform was designed to support measurements from 2 GHz to 10 GHz. For more information contact Dr. J. Salazar, Dr. C. Fulton and A. Umayama.
