METHOD AND DEVICE FOR DETERMINING AN ANGLE OF AZIMETH AND / OR ELEVATION IN A MULTI-BEAM RADAR SYSTEM

摘要

P Multi-beam radar system for determining the azimuth and / or elevation angle of a target. Method according to which at least two beams (22) are received. The amplitude of each echo signal is normalized (23) and to determine the angle of the objective, the normalized amplitude of each beam is compared with the diagram values (21) of a normalized antenna diagram ( 24) stored. The result of the comparison is combined (27) and the angle of the radar objective is defined as the one whose operating magnitude meets a minimum or maximum criterion (28). The angle-dependent operating variable contains the phase of at least two received echo signals (25-27). Normalization can also be applied to complex values. /P
