A radar sensor having a corresponding evaluation and control device, which has a measuring mode for locating radar targets and a blindness detection device, which is configured to detect blinding of the radar sensor with the aid of the signals received by the radar sensor itself; wherein the evaluation and control device has a test mode, in which the radar sensor is controlled on the basis of parameters that are different from the parameters for the measuring mode and optimized for the blindness detection device, and the evaluation and control device has a switching device for switching over between the measuring mode and the testing mode.

Method and radar system for determining the directional angle of radar objects

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.
