Vaisala Weather Radar WRK200


For customers who require coherent transmitter, Vaisala Dual Polarization Doppler Weather Radar WRK200 is equipped with klystron transmitter technology. WRK200 offers exceptional spectral purity and phase noise performance. Vaisala dual polarization technology supports already proven applications like HydroClass™ - real time operational hydrometeor classification software. This software is the first COTS product that uses real time polarization measurement for classifying targets into categories such as hail, snow pellets, snow or rain. It can also be used to identify and filter out non-meteorological targets.

Vaisala Weather Radar provides accurate measurement, easy maintenance access, low maintenance costs, semi-yoke style antenna/pedestal with a low momentum of inertia and weight. All hardware and software used in WRK200 radar has been optimized for superior dual polarization data quality. From excellent dual pol performance antenna to latest dual polarization signal processing algorithms.
