Abstract: A multibeam radar sensor is proposed in which a holder (of resilient construction) for polyrods, in connection with a spacing element, holds the polyrods fixedly at a predetermined spacing, preferably in the range between 0 mm and 0.2 mm. The stays of the holder are fashioned such that a spring force constantly presses the spacing element against the base plate. In this context, the spring force is chosen such that the maintenance of the predetermined spacing a is ensured even under disadvantageous operating conditions such as vibration, shock, and impact.

Abstract: According to the invention, a multi-beam radar sensor for microwaves is proposed, in which between a lens and the transmitter/receiver elements (6), focusing bodies (1) are disposed in such a way that they prefocus the radiation of an applicable transmitter/receiver element (6) with respect to the dielectric lens (8). The focusing bodies (1) are retained by a dielectric plate (2), into which a mount (4) is inserted. The mount (4) is embodied with regard to its material and geometric dimensions such that the least possible coupling between the individual focusing bodies (1) occurs. To attain this object, the mount (4) is embodied by recesses (5) in the regions between the focusing bodies (1). For simpler assembly and adjustment, bores (3) and adjustment openings (10) are provided.

Abstract: A multi-beam radar sensor having at least two transmitting/receiving patches, in which the patches, assigned polyrods, and/or a dielectric lens are configured so as to be asymmetrical. As a result of this asymmetrical arrangement, asymmetrical beam paths result for the transmitting and receiving beams. These asymmetrical beam paths cause the average error amount in the angle measurement of the radar sensor to be less than in the case of a symmetrical arrangement.

Abstract: The present invention relates to a method and an apparatus for adjusting the alignment of a beam characteristic of a distance sensor, in particular of a proximity radar for a motor vehicle. An apparatus for positioning a motor vehicle, preferably a headlight aiming device, is joined to the target object for the distance sensor. Also provided is a service unit with which measured values or data of the distance sensor can be read out. On the basis of at least one predefined criterion, the measured values or data are analyzed in such a way that necessary displacement directions of the distance sensor can be displayed by way of the service unit. Preferably the capability of the distance sensor to determine angular positions of detected target objects is utilized. Otherwise adjustment is performed to predefined reception levels.
