Compact Dual Polarimetric X-band Doppler Weather Radar WR2120


Dual Polarization

High precision rain observation & accurate measurements

The Dual Polarization of the WR2120 recovers signal intensity loss and attenuation caused by heavy rain.

Particle classification

Several data such as echo strength or phase difference, provided by the WR2120, can be utilized to assess the nature of the detected particle and deduct whether it is Snow, Hail or Rain.

Easy installation
  • Very compact and lightweight (ø1m, 65 kg)
  • No heavy equipment required for installation
  • Compatible with regular power outlet
Reduced operating costs
  • Solid-State
    -Reliable, less maintenance, long life solid-state transmission device
    -Low power consumption(100V, 200W)
High resolution & accurate measurements
  • Outputs dual polarimetric Doppler information (Zdr, Kdp) for computing diameter of precipitation particles as well as discriminating types of precipitation (rain, snow, etc.)
  • 3D scan to observe the vertical structure of a cumulonimbus
Various software applications available

Various data format compatibilities

Various data formats used in major software packages, such as Baron Lynx and Vaisala IRIS Focus, are available

Carbon fiber antenna dish
  • Reduction of the antenna weight
