[0003] According to engineering practice experience, it is relatively easy to obtain on-site records reflecting underground cavities and pipeline cavities by using ground radar, but it is still difficult to obtain the volume information of the detection target; The detection of these defects is limited to qualitative explanations, and the specific severity of the disease cannot be estimated quantitatively. Therefore, it is difficult to accurately and in-depth assess and monitor the quality of the underground, and it is difficult to make a decision on the scope and amount of reinforcement of the defects. Therefore, it is of great significance to establish a mathematical structure calculation model based on ground radar detection to obtain the equivalent volume of the measured target.
