Research Abstract

We investigated the method to estimate 3-D image of a buried object with directional borehole radar using dipole array antenna. We proposed the array signal processing to estimate the 3-D image with array data, which is acquired at multiple depths. Using this method, we estimate the 3-D image of the faults in Nakatatsu mine actually. This estimation results are reasonable, since the radar estimation agreed to the images, which was estimated by observation of boring cores and gallery wall.
