The invention relates to a driver assistance device () for a vehicle (), which driver assistance device has a radar appliance () for determining at least one measured variable (&#x3b1;, &#x3b1;, R, R) referenced to an object () that is external to the vehicle, wherein the radar appliance () comprises:

Driver assistance device for a vehicle and method for operating a radar device

The invention relates to a driver assistance device () for a vehicle (), having a radar apparatus () for detecting objects which are external to the vehicle, which radar apparatus () has an antenna unit () for irradiating and/or receiving electromagnetic waves (S, S) and a damping element () which is coupled to the antenna unit () and has the purpose of directing and damping the electromagnetic waves (S, S), by means of which damping element () the antenna unit () can be coupled to a transmitter and/or receiver device () of the radar apparatus (), wherein the damping element () has a branching unit () with a first line branch () for directing the damped electromagnetic waves (S, S) between the transmitter and/or receiver device (), on the one hand and the antenna unit () on the other, as well as a second line branch () which is coupled to the first line branch () and is terminated with a reflection-free terminating element (). The invention also relates to a corresponding method.

Driver assistance device for a vehicle, vehicle and method for operating a radar apparatus

The invention relates to a radar sensor () for use with automobiles. Said radar sensor emits pulsed radiation. The radar sensor is characterized in that it comprises an antenna with at least one layer-structured block () consisting of metal layers () which are arranged according to the Yagi principle and which are respectively separated from each other by a dielectric intermediary layer (). At least one of the metal layers () is excited by a supply system () with a radar frequency.

Radar sensor for use with automobiles

A radar system with a radar sensor () which comprises a transmitting module (), a receiving module () and a supply network (), wherein the transmitting module () comprises a first plurality of partial antennas () and the receiving module () comprises a second plurality of partial antennas (), and wherein the supply network () operates at least one partial antenna () of the transmitting module () together with at least one partial antenna () of the receiving module () in a first operating mode, to obtain a first, low angular resolution, and wherein the supply network operates one group of partial antennas () of the transmitting module () together with a group of partial antennas () of the receiving module () in a second operating mode to obtain a second high angular resolution. The radar system is characterized in that the supply network () operates at least one partial antenna () of the transmitting module () together with a group of partial antennas () of the receiving module () or a group of partial antennas () of the transmitting module () together with at least one partial antenna () of the receiving module () in a further operating mode.
