- Model WR-2100 - Compact Dual Polarimetric X-Band Doppler Weather Radar

0

FURUNO, which maintains the leading market share in marine Radar now presents its two X-band Weather Doppler Radars, the single polarimetric WR110 and the dual polarimetric WR-2100. With ultra-high spatiotemporal resolution capability, the two Radars can gather 50-meter-mesh omnidirectional precipitation intensity in six-second intervals. The WR110 single polarimetric Radar is extremely efficient for normal rain observations. The WR-2100 allows for even more sophisticated observations including three-dimensional analysis of heavy precipitation cumulonimbus and localized rainfall prediction. By creating a “Multi-Radar system” consisting of synchronizing several WR-2100 and WR110 Radars real-time 3D monitoring of meteorological phenomena can be achieved with an affordable and reasonable investment.

Compact, lightweight and Solid-state
Our Weather Radars utilize solid state technology reducing overall operating and maintenance costs thanks to low power consumption and fewer required replacement parts. Moreover our solid state technology provides high precision monitoring of precipitation with a wide range of signal processing and data format capabilities.

Simple and quick installation
No heavy machinery needed to transportation or install the Radar. It can easily be installed by a two person crew. Power requirement is a standard AC power outlet used for domestic appliances (100V/200V). The Radar can be installed practically anywhere without special structures or configurations.

By increasing the number of Radars it is possible to cover a wider area.

Also when installed in the same area the Radars observation data can be combined, further increasing accuracy, providing vector Doppler velocities and enhanced 3 dimensional imaging.

Increased observation range

High precision measurements


Reduced blind areas

Used for large Radar (S/C-band) supplement


FURUNO X-band Radars can supplement, reinforce and fill-in areas that other global surveillance weather Radars cannot reach.

*the example diagram on right shows an efficient combination using FURUNO X-band Radars to detect local weather changes with high precision in lower elevation areas where large S/C band Radars cannot access. The S/C Radars sweep the higher elevations for longer range surveillance.

FURUNO has decades of technical expertise in marine Radar development and is the clear leader in this industry. FURUNO, in close collaboration with many universities and other business organizations has now developed Radar solutions for meteorological monitoring and analysis. FURUNO's high resolution, compact X-band Doppler Weather Radar has proven essential for forecasting localized weather disturbances and other specialized applications including fire and volcanic ash detection. With new tools and solutions specifically designed for weather forecasting and observation, FURUNO’s objective is to provide safety to individuals and their property by presenting highly detailed information of potential meteorological events.

A radar capable of understanding extreme weather better than any other


There are a number of differing opinions globally on how to approach problems caused by extreme weather. These include short localized rainstorms, snowstorms, tornadoes, landslides and other life threatening phenomena that are increasing worldwide. Subsequently the urgent need for more localized weather forecasting is required in order to protect human life and assets against these unexpected natural disasters.

Numerous fields of application

FURUNO’s new weather Radars are compact and easily installed on building roofs and mountain tops. This is something inconceivable even a few years ago. Both ease of installation and transportability allows flexibility for countless applications and utilizations. These Radars provide comprehensive disaster prevention solutions for all situations.
