Lifting of radome base for OU-PRIME
Installation of 8.5-meter dish for OU-PRIME
Completion of radome for OU-PRIME
Commissioning of OU-PRIME on April 4, 2009
OU-PRIME after completion, September 2009

OU-PRIME (Polarimetric Radar for Innovations in Meteorology and Engineering) is an advanced Doppler weather radar. It was completed in January 2009 after a ten-month construction period and commissioned on April 4, 2009.[1][2] It is operated by the Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU). The radar was manufactured by Enterprise Electronics Corporation to provide OU students and faculty a platform for research and education in the field of radar meteorology. This C-band polarimetric radar has the highest resolution of any C-band, polarimetric, research, weather radar in the United States and possibly the world.[1][2][3][4]


OU-PRIME was struck by lightning on 19 March 2012 around 9:20am local time. Since then, the radar has not been operated due to damage.[1]


System characteristics

OU-PRIME, aka OU', is located on the Research Campus of the University of Oklahoma within walking distance of the National Weather Center building. Through a unique design, OU-PRIME can provide real-time time-series data providing opportunities for rapid developments in radar signal processing algorithms. Because of its C-band wavelength and 1 MW transmit power, OU-PRIME is extremely sensitive to clouds with approximately 10 dB more sensitivity over the NEXRAD system (S-band).

  • Minimum Detectable Signal: -112 dBm
    • Radar Sensitivity: -15 dBZ at 50 km
    • Noise Figure: 3 dB
  • Simultaneous dual-polarization
  • Flexible computing platform for real-time algorithm development
  • Real-time I/Q data recording/processing
    • A/D converter resolution: 16 bit
    • Receiver bandwidth: 6 MHz
    • Gate spacing: 25–500 m
    • Number of range gates: up to 2200
    • Clutter suppression: 60 dB (automatic detection/suppression using CLEAN-AP [1])
    • Advanced signal processing framework based on new STEP algorithm, including clutter estimation/suppression and multi-lag moment estimation
