Utilising the technical expertise FURUNO has accumulated through the development of marine Radar that has earned the leading market share, FURUNO, in close collaboration with universities and other business organisations, is now working on development of solution for meteorological monitoring and analysis. FURUNO's high quality compact X-band Doppler Weather Radar is indispensable for localised weather forecasting to materialise better safety in the society where the impact arising from the meteorological disasters can be diminished.
FURUNO's solution for meteorological monitoring and analysis
Soaring needs for Weather Radar that stem from intensifying extreme weather
A number of arguments on the global scale as to how to tackle problems arising from extreme weather, such as short localised rainstorms, tornados and other adverse phenomena, have been taking place recently. Subsequently, urgent needs have been recognised for the solution of localised weather forecasting as part of social infrastructure so as to protect human lives and assets from unexpected natural disasters, i.e., river floods, landslides, etc., hence delivering better safety and peace of mind to the society.
Doppler Weather Radar utilising solid state technology
By utilising solid state technology, the operating cost can be reduced thanks to lowering of power consumption as well as replacement of consumables. Moreover, high precision monitoring of precipitation is facilitated through a wide range of signal processing capability brought about by the solid state technology.
Dual Polarimetric Doppler Weather Radar to contribute to prediction of occurrence of rainstorms
Dual Polarimetric Doppler Weather Radar simultaneously transmits and receives horizontally- and vertically-polarised radio waves. It is capable of computing the movement velocity of nimbus, as can be obtained from Single Polarimetric Doppler Weather Radar using horizontally-polarised radio waves, as well as precise precipitation intensity.
Shape of precipitation particles is horizontally-long oval, due to the effect from atmosphere and gravity.
Using these characteristics, Dual Polarimetric Doppler Weather Radar obtains diameters of precipitation particles to compute precise precipitation intensity.

In order to predict the development of short localized rainstorms, which follows the abrupt development of a cumulonimbus, high spatiotemporal resolution monitoring of meteorological phenomena is required. By downsizing both Dual Polarimetric Doppler Weather Radar and Single Polarimetric Doppler Weather Radar, FURUNO makes remarkable reduction on the deployment cost a possibility. Also, it has become easier to create “Multi-Radar System” by combining both Radar units.
High spatiotemporal resolution 3D monitoring of meteorological phenomena by “Multi-Radar System” makes possible the provision of precautious information about prospective sediment disasters as well as information about evacuation routes, shelter location, etc., in case of foreseen rainstorms in real-time.

Classified as one of the smallest and lightest Weather Radar available in the market(*)
FURUNO, which has earned the leading market share in marine Radar, provides Dual Polarimetric X-band Doppler Weather Radar WR-2100 and Doppler Weather Radar WR-50.
With ultra high definition spatiotemporal resolution capability, the WR-2100 Dual Polarimetric Doppler Weather Radar grasps omni-directional precipitation intensity in 50-metre-mesh in six-second-intervals. By conducting high spatiotemporal resolution monitoring of the development process, three-dimensional structure as well as movement of a cumulonimbus, which causes precipitation, the development of short localised rainstorms can be predicted. Moreover, the WR-2100 has been downsized during the development phase to the extent that can be classified as one of the smallest and lightest Dual Polarimetric Doppler Weather Radar available in the market.
Combining the WR-2100 tohether with the WR-50, which conducts high-speed detection of movement of the nimbus, FURUNO delivers “Multi-Radar System” capable of conducting real-time 3D monitoring of meteorological phenomena at a modest investment.
