The Hurricane Imaging Radiometer (HIRAD) is an airborne imaging, single-pol passive C-band radiometer. It measures brightness temperature, which is used to determine rain rate and wind speed. HIRAD operates at four frequencies (4, 5, 6, and 6.6 GHz) and has a typical spatial resolution of 1-3 km. HIRAD’s design is built upon the Stepped Frequency Microwave Radiometer (SFMR), with the addition of wide-swath measurement capabilities.
