Doppler Radar – 3S-Doppler
The Doppler Radar serves as a tool to accurately measures the speed of various condensed water forms such as rain, freezing rain, hail, snow, and sleet. Its low-energy sensor efficiently detects precipitation right from the initial drop. With extensive applications across hydrology, water management, agricultural sciences, environmental studies, building automation, meteorology, airport operations, and traffic control, the radar's capabilities are virtually boundless.
