Spatial Prediction Method for Underground Structures in Key Red-soil Zones Based on Ground Penetrating Radar

The invention relates to a method of spatial prediction for underground structures of key red-soil zones based on a ground penetrating radar, which includes Step A, to construct a database of underground structure of target key red-soil zones; Step B, to measure target key red-soil zones and obtain radar image data of target key red-soil zones; Step C, to interpret radar images of target key red-soil zones and obtain radar image interpretation results; Step D, to update the database of the underground structure of the target red soil key zones; Step E, to construct a three-dimensional prediction model of the underground structure of the target red soil key zones, and to obtain the spatial distribution of different layers of the underground structure of the target red soil key zones. The designing method can not only give a key zone's detailed structure definition, database construction and ground penetrating radar operation process, but also quantify the spatial coupling relationship between the thickness/type of a key zone structure and environmental variables.
