According to engineering practice experience, the geological radar can be used for easily obtaining records reflecting underground cavities and pipeline cavities on site, but if the volume information of a detection target body is further obtained, the difficulty is not small; because the detection of the defects is limited only in qualitative explanation at present, and the specific severity of the disease cannot be quantitatively estimated, the underground quality condition is difficult to accurately and deeply evaluate and monitor, the reinforcement range and the reinforcement amount of the defects are difficult to effectively evaluate, and some specific measures cannot be taken in advance for remediation, so that the method has important significance for establishing a mathematical structure calculation model for obtaining the equivalent volume of the detected target body according to the geological radar detection.
The traditional radar detection circuit has a narrow detection range, so that the exploration of complex terrains is limited, geological data cannot be surveyed in a large range, and geological information can not be accurately obtained; the interference of an electromagnetic field can be caused when complex geology is surveyed, so that the radar detection circuit is interfered when receiving echoes, and the survey information can not be accurately obtained.
