Abstract
A monostatic multi-beam radar sensor includes a group antenna and a mixer system made up of a plurality of transfer mixers connected to antenna elements of the group antenna. A first number of the transfer mixers is switched to isolation mode and a second number of the transfer mixers is switched to transfer mode in order to realize different directional characteristics for the transmit and receive operation.

A monostatic multi-beam radar sensor, comprising:
- a group antenna having multiple antenna elements;
- and
- a mixer system including multiple transfer mixers connected to the antenna elements of the group antenna;
- wherein a first subset of the transfer mixers is switched to isolation mode and a second subset of the transfer mixers is switched to transfer mode in order to realize different directional characteristics for a transmit operation and a receive operation.
A method for operating a monostatic multi-beam radar sensor having (i) a group antenna including multiple antenna elements and (ii) a mixer system including multiple transfer mixers connected to the antenna elements of the group antenna, comprising:
- switching a first subset of the transfer mixers to isolation mode;
- and
- switching a second subset of the transfer mixers to transfer mode;
- wherein different directional characteristics are realized for a transmit operation and a receive operation by the switching of the first subset to isolation mode and the switching of the second subset to transfer mode.
