APPARATUS FOR MAPPING BURIED OBJECT AND GROUND CAVITY THROUGH ELECTROMAGNETICWAVE ANALYSIS

摘要

The present invention, a moving unit moving in a first direction in a specific exploration section on the ground; A surface transmission radar that transmits directional electromagnetic waves to the ground of the exploration section and receives reflected waves reflected from underground structures; And the first reflection wave reflected from the specific reflection point of the underground structure at the first point of the surface transmission radar in the specific exploration section and the second reflection wave reflected from the same specific reflection point at the second point, , Calculates coordinates by calculating the length and depth of the specific reflection point, and continuously changes the first and second points of the surface transmission radar according to the movement of the moving unit by a specific exploration line interval to obtain the distribution coordinates of the specific reflection point. Analyzing, the control unit for mapping and evaluating the length and depth and shape of the underground structure; including, to evaluate the specific shape and size of the underground structure, discloses a mapping device for underground structures and joints through electromagnetic wave analysis.
