Multi-beam radar sensor e.g. automobile obstacle sensor, has focusing body supported by holder relative to each transmission/reception element and common dielectric lens in path of each beam

摘要

The radar sensor has a number of transmission/reception elements (6) mounted on a carrier (7) and a focusing body (1), fixed in place at a given distance from each transmission/reception element by a holder (4), with a common dielectric lens (8) in the path of each beam. The holder material, its geometric shape and/or its points of contact with the focusing bodies are selected for minimising the energy coupling between the adjacent focusing bodies. An Independent claim for a distance holder for a radar sensor is also included.
