摘      要：In order to obtain the global precipitation distribution data,this paper investigates the precipitation distribution model,the normalized radar cross-section model,and the retrieval algorithm with X-band synthetic aperture radar（X-SAR）.A new retrieval algorithm based on the surface-scattering reference attenuation is developed to retrieve the rain rate above the ground *** new algorithm needs no statistical work load and has more extensive *** using the new algorithm for three cases verify that the rainfall is retrieved with high precision,which proves the capability of the algorithm.
