REMOVAL METHOD FOR INTERFERENCE WAVES

摘要

PROBLEM TO BE SOLVED: To provide a method in which interference waves applied to a radar apparatus are removed through a digital-signal processing operation without using a dedicated receiving system. SOLUTION: The sum signal and the difference signal of signals induced in two directional antennas, which are arranged to be separated, are multiplied by a processing function corresponding to an angle of incidence decided by the interval between the antennas and the wavelength used. An angle for which the cumulative value of the absolute values of their difference outputs becomes minimum is found.
