Abstract: Geology radar,which is used widely in the geological prospecting investigation,is a powerful tool using in shallow geological survey to detct faulted zone,fractured zone,water abundant zone and karst caves.In this pa-per,the actual radar geological prospecting works on the basis of applications,the establishment of the geological characteristics of the radar images of several common with the typical geological phenomenon counterparts,for future geological radar image analysis and the basis of identification,conducive to the use of ground penetrating radar images to discriminate analysis and geological phenomena accumulation of geological interpretation of the radar images experience.
