Abstract:
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 having a transmitter device and a receiver device; a signal processing means; a data storage means; and a graphical interface means, wherein said area of interest is previously referenced and said radar is a ground penetration 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 steps , wherein said transmitted signal is mixed with the received or reflected signal for each step, resulting in two sets of values corresponding to the phases of each frequency step, and wherein the two sets of values obtained over successive scannings are stored in the storage means and subsequently processed in processing means for obtaining a final image of the location of said objects above the ground and below the ground, wherein the obtained object image is calibrated with distances and heights comprising spatial coordinate data, and wherein said processing means further geometrically encode the final image by determining a code for each measured point of said area of interest and assigning said code to said each measured point.
