Hurricane Wind Speed

Stepped Frequency Microwave Radiometer (SFMR)

The Stepped Frequency Microwave Radiometer (SFMR) developed by ProSensing has been used by the National Oceanic and Atmospheric Administration (NOAA) aboard their hurricane reconnaissance aircraft to measure over-ocean wind speed and rain rate in hurricanes and tropical storms. The SFMR is a compact, airborne radiometer designed to measure surface brightness temperature in 6 frequency bands spanning 4.5 to 7 GHz.
