Embodiment Construction

[0048] Within the scope of this patent application, a radar system is to be understood as any system which, on the basis of emitted and reflected electromagnetic waves, can localize objects that reflect back electromagnetic waves.

[0049] Within the scope of this patent application, an antenna element is to be understood as any element which is designed to receive electromagnetic waves and convert them into electrical signals. The antenna element can be constructed, for example, as a copper plane on a printed circuit board ( ). The antenna elements can also be configured in the form of rods or the like.

[0050] Within the scope of this patent application, a radio signal is to be understood as any transmitted or received electromagnetic wave.

[0051] Within the scope of this patent application, a computing device may be any electronic device capable of performing calculations. It may be, for example, a microcontroller, microprocessor, computer, application specific integ...

Abstract

An antenna array, particularly for a radar system, having first antenna elements which are situated in a horizontal direction in a plane and which are developed to receive a first radio signal, having second antenna elements which are each situated above or below the horizontally situated first antenna elements and which are developed to receive the first radio signal, and having a processing device which is developed to calculate an azimuth angle and an angle of elevation of an object, that is located in front of the antenna array, from the radio signal received by the first antenna elements and from the radio signal received by the second antenna elements. Also described is a radar system, a vehicle and a method.

Description

technical field [0001] The invention relates to an antenna arrangement, in particular for a radar system, to the radar system, to a vehicle and to a method. Background technique [0002] Even though the invention is described below in connection with a radar system for a vehicle, the invention is not limited thereto but may be used with any radar system. [0003] Many electronic systems are used in modern vehicles, which can be used, for example, to support the driver when guiding the vehicle. For example, the brake assist can detect a road user driving ahead and brake and accelerate the vehicle accordingly so that a predetermined minimum distance to the road road ahead is always maintained. This brake assist can also initiate emergency braking when it detects that the distance to a preceding road participant is too small. [0004] In order to be able to provide such assistance systems in a vehicle, it is necessary to detect data about the surroundings of the respective ve...
