C-band fully Coherent Doppler weather Radar (GR-18)

A C-band fully coherent Doppler weather radar with a detection range of up to 400 km for precipitation intensity and 200 km for velocity/direction. It’s used by the China Meteorological Administration to monitor and provide early warnings for disastrous weather like typhoons, hailstorms, and tornadoes. It has applications in military and civil aviation for crucial weather support.

Category:

The GR-18 C-band fully coherent Doppler weather radar can not only determine the location and intensity of precipitation, but also determine the velocity and direction of the airflow inside the precipitation. Precipitation distribution and regional precipitation within a radius of 200 kilometers can be accurately estimated, and disastrous weather such as typhoons, rainstorms, squall lines, hail, tornadoes and other disastrous weather within a distance of 400 kilometers can be effectively monitored and early warning.
