14 GHz FM-CW/pulse-compression radar for observation of precipitation on a satellite-earth path
Abstract
An FM-CW/PC radar for observation of precipitation on slant-paths is presented. The radar system constant is calibrated by comparing the attenuation estimated from the radar data with that derived from the sky noise temperature. Relations between the attenuation coefficient and the effective radar reflectivity factor needed for attenuation estimation are determined for each rainfall event by using the raindrop size distributions measured on the ground by a disdrometer. From the calibration, the radar sensitivity is determined to be almost equal to that expected from the radar design.
