Abstract: Provided is a radar sensor comprising at least one antenna 1 having a FOV 2, at least one RF absorber 9, and a radome 3 covering the at least one antenna 1 and the at least one RF absorber 9, wherein the at least one RF absorber 9 is provided with a top surface 10 comprising at least one scattering structure configured to redirect radar waves out of the FOV 2 and to increase radar wave scattering interactions with the radome 3 and the at least one RF absorber 9. As a result, energy of scattered waves and of backwards radiation is reduced. Further, the amount of RF absorber material is reduced and the RCS of the radar sensor is reduced.

Abstract: A radar system includes a transmitting element adapted to transmit a radar signal, a receiving element adapted to receive a reflected signal of the radar signal being transmitted by the transmitting element, and a radome covering the transmitting element and the receiving element and having an inner surface and an outer surface. The inner surface of the radome faces the transmitting element and the receiving element. The radome comprises a recess being located at the inner surface.

Abstract: A mounting bracket for a radar sensor is provided. The mounting bracket comprises a first layer and a second layer positioned adjacent to the first layer. The second layer has a higher absorption coefficient than the first layer for radar waves having a wavelength in a predetermined range of wavelengths. The mounting bracket is configured to be mounted in a predefined orientation such that the first layer is first exposed to radar waves transmitted by the radar sensor before the second layer is exposed to the radar waves. A radar system including the mounting bracket and methods for manufacturing the mounting bracket and for integrating the radar system in a vehicle are also disclosed.

Abstract: A method for predicting a false positive detection by a radar sensor includes simulating a radar signal, determining a plurality of reflected radar signal rays based on the simulated radar signal and data regarding at least one vehicle component that may be a source of a false positive detection based on received reflected radar signal rays, selecting detectable rays from the reflected radar signal rays, determining an energy level for each detectable ray based on a reflectivity of the at least one vehicle component, clustering at least some of the detectable rays based on a distance between a reflection origin location of at least two of the detectable rays being within a predefined range, determining an energy level of clustered detectable rays, and determining a false positive based on the determined energy level of the clustered detectable rays being above an energy threshold.
