[. . . ] www. vaisala. com Vaisala Weather Radar WRK100 Features/Benefits 250 kW Klystron transmitter with low-maintenance solidstate modulator Vaisala's light-weight, semiyoke-style pedestal 1 degree beamwidth low side lobe antenna Modular double-cabinet design Built around Vaisala Sigmet RVP900 signal processor Wide dynamic range digital IF receiver Fully programmable scanning Comprehensive BITE Integral flat screen display for local maintenance Remote control/monitoring Improved interference filtering Feed forward control loop to allow extremely fast and precise antenna movement Options: - Built-in automatic calibration - Dual polarization upgrade ready High-Performance and Reliability The WRK100 is Vaisala's single polarization C-band klystron Doppler Weather Radar. [. . . ] Vaisala Sigmet software provides comprehensive radar product generation, display and forecasting features. Integration to other Vaisala systems such as lightning detection networks, rain gauge, LLWAS and surface weather is available. Engineered for Remote Operation For most customers, unattended remote operation is essential. The WRK100's comprehensive remote control, BITE and active monitoring features allow radar maintenance to be coordinated from a central facility. The detailed level of fault reporting allows maintenance personnel to accurately assess any problem before traveling to the radar site. The benefit is reduced MTTR and higher data availability. Investment Protection for the Future The service life of a modern weather radar system can be over 15 years, during which time there will be major technology advances. Vaisala's modular approach and use of accepted open interface standards is designed to make the WRK100 upgradeable in the future. For example, the system can be purchased as dual-pol ready, or upgraded in the field to dual polarization.
