Mobile Rapid Scanning X-Band Polarimetric Weather Radar

RaXPol data collected from a tornadic storm on May 24, 2011.

Rapid Scanning X-band Polarimetric Radar (RaXPol)

Developed for the University of Oklahoma http://arrc.ou.edu/raxpol.html with funding from the National Science Foundation, RaXPol generates rapidly updated images of tornadic storms. Using a high performance 2.4 m diameter dual-polarization antenna, and equal-power V/H polarization on transmit, RaXPol can generate full-storm volume images of reflectivity, Zdr, Kdp, and HV correlation coefficient in less than 30 seconds. 

RaXPol Features

  • heavy duty pedestal with 180 deg. per second scan rate
  • 20 kW, 1% duty cycle Travelling Wave Tube Amplifier
  • 1 degree beamwidth 2.4 m diameter low sidelobe dual polarization antennna
  • PC-based 16-bit 2 channel digital receiver
  • Frequency-agile transmitter allowing rapid estimation of radar parameters
