Stepped Frequency Microwave Radiometer (SFMR) from ProSensing Inc.

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.

Calibrated values of brightness temperature generated by SFMR are reported in real time to a windspeed retrieval algorithm, developed in cooperation with NOAA's Hurricane Research Division. This algorithm generates a real time measure of surface level wind speed and rain rate in hurricanes and tropical storms.
