Method and device for determining an azimuth angle and/or an elevation angle in a multibeam radar system |
摘要 |
Method and device for determining an azimuth angle and/or an elevation angle, based on a multibeam radar system, in which the echo signals of each radar target are recorded over at least two beams. The amplitude of an echo signal recorded in each receiving beam is normalized. For each receiving beam, the normalized amplitude is compared to the pattern values of an antenna pattern stored and normalized for this beam in order to determine the angle of a radar target. The comparison results from at least two receiving beams are combined to form an angle-dependent analysis quantity, and the angle whose angle-dependent analysis quantity meets a minimum and maximum criterion is determined to be the angle of the radar target. Included in the angle-dependent analysis quantity is a phase angle of at least two recorded echo signals. This operation can also be performed on the basis of a complex normalization operation.
