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.
