The 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.
This 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.
The 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.
