ABSTRACT:
A system for detecting underground objects is disclosed wherein image data obtained through a deep range-migration correction and image data obtained through a shallow range-migration correction are combined so that data at the corresponding positions on both the image data at high level may mutually intensify, whereas other data may mutually weaken. The target spot on the thus combined image data is made sharp and provides sufficently high resolution.
