Underground Imaging Using Shear Waves –Study on Three Dimentional Underground Imaging–

We proposed an underground imaging technique that uses shear waves and a method based on the stacking of reflected scattered waves. In order to study a three-dimensional underground image, geophones were arranged in a plane and three targets were buried at different depths. We tried to detect these targets using cross-sectional images. From the experimental results, we were able to find the buried targets; however, improvements are necessary to make a three-dimensional image.
