 S
Band Full-Coherent Doppler Weather Radar
GLC-16A full-coherent
Doppler weather radar is a new generation
of weather radar netted in China, which
operates in S band and adopts Doppler signal
processing technology. It has great capability
to automatically generate disaster weather
alarm.
It also can automatically
generate and display various weather products,
and earlier detect the air current threatening
aviation (even in the clear sky) and catastrophic
flood, which improve the capability of detecting
and warning heavy catastrophic weather,
such as rainstorm, precipitation, wind shear,
tornado and hailstone, etc.

 X
Band Dual-Channel and Dual-Polarization
Full-Coherent Doppler Weather Radar
CLC-12 radar employs pulse
Doppler and dual-polarzation techniques,
which can not only estimate accurately the
distribution, regional precipitation and
phase state of rainfall particles in cloud
within a radius of 150km, but also efficiently
make surveillance and early warning for
catastrophic weather, such as typhoon, rainstorm,
hailstone, squall line, tornado, etc. within
a radius of 300km.
Due to the dual-polarization
function added on the basis of Doppler weather
radar, CLC-12 radar can obtain more information
about the shape and phase state of rainfall
particles. This radar has already been a
new powerful equipment for the weather detection.
