%X The precipitation radar (PR), the first space-borne rain radar, carried by Tropical Rainfall Measuring Mission (TRMM)satellite, has provided a new sounding method for atmospheric research and has played an important role in understanding the circulation of global energy and water for five years. In this paper, the data of Fuyang ground-based radar and PR data, both obtained from Huihe River Basin Experiment (HUBEX)in 1998 and 1999, have been compared in three aspects, 1) Distribution of echo intensity, 2) Averaged reflectivity profiles, 3) Sensitivity Analyses indicate that Fuyang radar is better than PR in sensitivity and horizontal resolution, but the observing error still exists in data because of attenuation-influence and beam-width influence. The farther the observed region is away from Fuyang radar station, the more difference between the observed value and true value is. The wavelength of PR is shorter than the Fuyang's therefore the PR is more sensitive to the attenuation in strong echo. Especially when the strong attenuation is encountered, the corrected echo value of PR is still smaller than the true value. The way of PR detecting precipitation clouds, from space to surface, is thoroughly different from Fuyang ground-based radar's. The PR data can easily avoid the attenuation-influence in horizontal direction. The vertical resolution of PR data is much better than the Fuyang's and the PR data is symmetrically distributed in spatial domain which is dislike Fuyang radar data, so a new effective method for correcting echo value of Fuyang ground-based radar is provided in this paper by comparing the averaged profiles of PR and Fuyang in different regions.
