Abstract
A ROSAR wire detection method is based upon ROSAR focusing of entire segments of wire. By generating a wire reference signal comprised of a sum of coherent reference signals, the basis for reliable wire detectability is provided.
Claims2
A method of operating a synthetic aperture radar system based upon rotating antennas (ROSAR) that operates at pulse frequency or in FM-CW operation to detect wire obstacles on the basis of a ROSAR focusing of entire segments of wire, said method comprising:
- establishing a wire reference signal from the sum of reference signals whose reflection points lie along a single line, which is shifted geometrically, taking into consideration differing transit times and doppler shifts;
- and
- correlating an entire received signal from a sector in which a wire obstacle may be situated, with the wire reference signal.
