<p>A system for wire detection comprising a transmitter (14) for transmitting multi-polarity waves, means for receiving waves reflected off target and means for analyzing the polarization of the reflected waves to detect linearly polarized echos characteristic of wires and to issue a warning indicative of the presence of a wire (11). The wavelength of the transmitted waves is larger than the diameter of the wires to be detected. A method for wire detection comprising the following steps, for each of a plurality of angles U between 0 and 180 degrees: transmit pulses of electromagnetic waves having a linear polarization at an angle U to horizontal; receive echoes at the same polarization angle U; and prepare a map (U, R) with the magnitude of the received echo for each angle U and each ground cell at range R.</p> |
