1. A system for detecting, locating and identifying objects above the ground and below the ground comprising an area of interest, an airborne vehicle circumscribing said area of interest, that is provided with a radar comprising an antenna with its respective transmitter and receiver device, signal processing means, data storage means and graphical interface means, wherein said area of interest is previously referenced and said radar is a ground penetration (GPR) radar of the heterodyne type in which signal transmitted by the antenna generates a light beam from a strip of land and consists of a sinusoidal electromagnetic signal whose frequency is varied in predetermined and accurate stepped stages, wherein said transmitted signal is mixed with the received or reflected signal, resulting in two sets of values corresponding to the phases of each frequency step or stage, and wherein these sets of values obtained over successive scannings, as the antenna moves, are stored in the storage means and subsequently processed in processing means for obtaining a final image or map of the location of said objects above the ground and below the ground.
