A method for determining a sides - and / or an elevation angle in the case of a multi-beam radar system and apparatus for carrying out the process

摘要

A method for determining a sides - and / or an elevation angle (α), in which there is a radar target relative to a reference system is located, based on a multi-beam radar system, in which the echo signals of each of the radar target are taken up by means of at least two beams (22, 31),– the amplitude of a received echo signal is normalized in each received beam (23, 32),– for each reception beam, the normalized amplitude (ne_k, upper level input nodes knes_k) with stored, normalized diagram values (nd_k(a), knd_k(a)) of an antenna pattern of the received beam is compared (24, 33),– the comparison results of at least two receive radiation to an angle-dependent an evaluation value (s (a)) are linked (27, 34) and– where the angle of the radar target that angle is determined, whose angle-dependent an evaluation value (s (a)) - a minimum or maximum criterion is fulfilled (28, 35),characterized in that, in the angle-dependent an evaluation value (s (a)), furthermore, a phase angle of at least two echo signals received is entered (25, 27, 32, 34).
