OU-PRIME
Polarimetric Radar for Innovations in Meteorology and Engineering

OU-PRIME OU-PRIME provides a state‐of‐the‐art platform supporting innovative radar engineering and meteorological projects by researchers, students, and educators. This unique, high‐resolution, dual‐polarization radar will also be used to enhance collaboration of the University of Oklahoma with academic, government, and private sector partners.

System Overview

Operated by OU's Advanced Radar Research Center (ARRC), OU‐PRIME is the highest resolution, dual‐polarization, C‐band, research radar in the world. The sensitivity of the system is excellent, opening up possibilities for studies of clear‐air phenomena and non‐precipitating clouds, for example. The hardware was designed to allow flexible configurations for both RF and digital technology investigations. Real‐time acquisition of time‐series data facilitates advanced signal processing developments such as spectral analysis, adaptive clutter filtering, etc.

Open for Collaboration

The University of Oklahoma encourages academic, government, and private sector collaborations focused on advancing weather radar technology and science. OU‐PRIME is open for business as a platform to foster and support such relationships. Joint projects are welcome in signal processing, radar system design, phased array radar, profiling radar, QPE, radar polarimetry, retrieval algorithms, and severe storm observations. Please contact the ARRC Director for specific inquires.
