ABSTRACT:
A system for detecting underground objects which uses reflected wave profile data collected for obtaining a detected image output and subjects the data to a sequence of synthetic aperture processing, in which set values of the dielectric constant are successively varied, and obtains the actual dielectric constant of the soil in which the targets are buried by evaluating the results of the synthetic aperture processing, whereby the need for special data collecting work only for obtaining the actual dielectric constant is eliminated.
