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.
Claims10
A multi-beam radar sensor comprising:
- at least two transmitting and receiving patches on a support;
- and
- at least one of assigned polyrods and a dielectric lens;
- wherein the radar sensor is monostatic and is arranged so that at least one of a transmitting beam and a receiving beam has an asymmetrical beam path with respect to a median plane of the radar sensor.
