Picture of Okinawa Electromagnetic Technology CenterThe Okinawa Electromagnetic Technology Center conducted research and development for three types of radio sensors. Our objective is to investigate the mechanisms of interaction between the ocean and the atmosphere, as it is well known that this interaction significantly affects global-scale climatological variations such as global warming. We also conducted additional atmospheric and oceanic observations, mainly in the maritime subtropical climate zone. In 2014, phased array weather radar and doppler lidar network fusion data system (PANDA) and Space optical communication system were completed.

phased array weather radar and doppler lidar network fusion data system (PANDA)

picture of phased array weather radar and doppler lidar network fusion data system (PANDA) The sudden, local weather disasters caused by localized bursts or tornados have been huge social issues. It is very important to investigate the 3D structure of precipitating cloud for the early detection, however, the conventional radar with parabola antenna could not correspond. Adopting the 1D phased array into this radar system improved the time resolution of observation dramatically.

Space Optical communications facility

picture of Space Optical communications facilityThis is an optical reflecting telescope used for space optical communication that makes the high-speed communication possible. This telescope can observe with 4 focuses including Nasmyth and Coude focus in addition to Cassegrain reflector, and tracks LEO satellite with a high degree of accuracy.


NICT Okinawa Bistatic Polarimetric Radar (COBRA) Nago Precipitation Radar Facility and Bistatic Receiver Station

picture of Nago Precipitation Radar Facility and Bistatic Receiver StationThe Okinawa Bistatic Polarimetric Radar is being developed to perform high-precision measurements of meteorological phenomena in the subtropical region, such as the three-dimensional structure of precipitation and winds accompanying typhoons. The results of this development will be used to verify the practicability of next-generation precipitation radar technologies.

The Computer Network System for Subtropical Environment Monitoring Rain

This is a computer network for the automatic acquisition, accumulation, and distribution of atmospheric and oceanic observation data collected at the Ogimi Wind Profiler Facility (NICT Ogimi), the Nago Precipitation Radar Facility (NICT Nago), the Ishigaki Ocean Radar Facility (NICT Ishigaki), the Yonaguni Ocean Radar Facility (NICT Yonaguni), and the Okinawa Electromagnetic Technology Center (NICT Okinawa).

The ground-based meteorological observation system

The ground-based meteorological observation system consists of three observation stations ( which are located in Ogimi, Nago, and Onna) and one monitoring station for surveillance and control of the observation stations. The system permits continuous ground-based observations of meteorological characteristics such as temperature, humidity, atmospheric pressure, wind direction, wind speed, solar radiation, and precipitation.
