Relations among rain parameters are calculated for the design of future spaceborne precipitation radar at 13.6 GHz and 35. 5 GHz. These rain parameters are rainfall rate R, radar reflectivity factor Z and attenuation coefficient k. These two frequencies will be used for the dual frequency precipitation radar on the GPM (Global Precipitation Measurement)… (More)
— We have developed a broad-band radar which is the precipitation Ku-band doppler radar using the pulse compression technique (bandwidth=80MHz), and observed the rainfall. We could successfully obtain the vertical profile of the equivalent reflectivity factor Ze and doppler velocity with the high range-resolution from low altitude.
