    • A compact, multi-beam motor vehicle radar sensor is described, which is placed in a housing, with an antenna arrangement consisting of a dielectric lens (15) and at least two first antenna feeds (161 to 163, 181 to 183), which are arranged along a first straight line (20) and form a first row of antenna feeds, wherein at least one further antenna feed (164 to 165, 184 to 185) is provided, which is arranged in such a way that at least one further row of antenna feeds is formed along a further straight line (21), wherein this further row can be congruently represented on the first row by a rotation around an imagined point of rotation (M). Such a motor vehicle radar sensor can be very simply and cost-effectively adapted to different installed positions.

    • 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.

    • A method and a radar sensor for determining an elevation angle error of a multibeam radar sensor are described. In order to detect an elevation angle of the multibeam radar system with respect to a predefined target, a plurality of laterally arranged cutting planes at a predefined distance are formed. The values of the corresponding antenna diagrams in each plane are stored in a suitable form, for example, normalized and in a parametric form taking into account the elevation angle &agr;. In order to reduce the size of the memory, it is sufficient to store one symmetry half for reasons of symmetry if additional information, for example, road clutter values are added, so that the upward or downward direction of the angle can be recognized. By comparing the measured echo values obtained by normalization and application of a quality factor, a corresponding elevation angle &agr; is obtained for each cutting plane. Using an appropriate histogram, an angle for the maladjustment of radar sensor can be determined from the measured values stored over a longer period of time.
    • 描述了一种用于确定多波束雷达传感器的仰角误差的方法和雷达传感器。 为了检测多光束雷达系统相对于预定目标的仰角,形成预定距离的多个横向排列的切割平面。 每个平面中对应的天线图的值以适当的形式存储,例如,考虑到仰角α的标准化和参数形式。 为了减小存储器的尺寸,如果添加附加信息,例如道路杂波值,则可以存储对称的一半对称半部,从而可以识别角度的向上或向下方向。 通过比较通过归一化和应用质量因子获得的测量回波值,对于每个切割平面获得相应的仰角α。 使用适当的直方图,可以从更长时间内存储的测量值确定雷达传感器失调的角度。
