Claim 3:
4. The method for detecting leakage of a water supply pipe based on ground-penetrating radar three-dimensional image attribute analysis according to claim 1, wherein said multi-attribute analysis in the step 4 comprises analysis on coherent attributes, instantaneous attributes, frequency attributes and amplitude attributes; and
an attribute analysis profile and an attribute analysis type are determined according to a three-dimensional space information map constructed in the step 3, and a corresponding attribute type is selected according to an Attribute module in an analysis function of the OpendTec; firstly, the coherent attributes are applied to the horizontal profile to quantify similarity of radar waveforms in axial and vertical directions, so as to acquire three-dimensional space information of pipe leakage and obtain a suspected leakage point; secondly, the instantaneous attributes are applied to the longitudinal profile to highlight horizontally continuous slight changes, and then the frequency attributes are applied to the transverse profile to obtain a spectrum with rich information.
