The Hurricane Imaging Radiometer (HIRAD) is an airborne microwave radiometer developed to provide wide-swath hurricane surface wind speed and rain rate imagery for scientific research. This letter presents a geometric evaluation of the brightness temperature (Tb) images produced by HIRAD for high-contrast land/water targets. Methodologies used to validate geolocation accuracy and spatial resolution...
The Hurricane Imaging Radiometer (HIRAD) is an experimental C-band airborne microwave radiometer developed by NASA Marshall Space Flight Center (MSFC) to provide hurricane's surface wind speed and rain rate. It is intended to expand the current NOAA and US Air Force hurricane surveillance capability by extending the operational Stepped Frequency Microwave Radiometer (SFMR) measurements to a wide-swath...
Microwave remote sensing observations of hurricanes, from NOAA and USAF hurricane surveillance aircraft, provide vital data for hurricane research and operations, for forecasting the intensity and track of tropical storms. The current operational standard for hurricane wind speed and rain rate measurements is the Stepped Frequency Microwave Radiometer (SFMR), which is a nadir viewing passive microwave...
Microwave remote sensing of surface wind speed and rain rate in hurricanes is critical to predict their growth and movement as they develop and make landfall. The Hurricane Imaging Radiometer (HIRAD) is an experimental airborne microwave radiometer developed by NASA Marshall Space Flight Center (MSFC) to provide ocean surface wind speed and rain rate measurements in hurricanes. It is intended to expand...
