Abstract
In accordance with an embodiment, a radar device includes transmit circuitry configured to emit a radar signal including a plurality of frames each comprising a respective sequence of chirps. The transmit circuitry is further configured to wirelessly emit information about the radar signal to a surrounding environment. The information indicates at least one of a positioning of sequential chirps with respect to each other for at least one of the plurality of frames and a positioning of sequential frames with respect to each other in the radar signal.
Claims20
A radar device comprising transmit circuitry configured to:
- emit a radar signal including a plurality of frames that each comprise a respective sequence of chirps;
- and
- wirelessly emit information about the radar signal to a surrounding environment, the information indicating at least one of:
- a positioning of sequential chirps with respect to each other for at least one of the plurality of frames, or
- a positioning of sequential frames with respect to each other in the radar signal.
A method for a radar device, the method comprising:
- emitting a radar signal including a plurality of frames that each comprise a respective sequence of chirps;
- and
- wirelessly emitting information about the radar signal to a surrounding environment, the information indicating at least one of:
- a positioning of sequential chirps with respect to each other for at least one of the plurality of frames;
- or
- a positioning of sequential frames with respect to each other in the radar signal.
A radar device comprising:
- transmit circuitry configured to emit a radar signal;
- and
- receive circuitry configured to receive from a further radar device information about a further radar signal emitted by the further radar device, wherein the further radar signal includes a plurality of frames that each comprise a respective sequence of chirps, and wherein the information about the further radar signal indicates at least one of:
- a positioning of sequential chirps with respect to each other for at least one of the plurality of frames, or
- a positioning of sequential frames with respect to each other in the further radar signal,
- wherein the transmit circuitry is configured to dynamically adapt at least one parameter of the radar signal based on the information about the further radar signal.
A method for a radar device, the method comprising:
- emitting a radar signal;
- receiving from another radar device information about a further radar signal emitted by the further radar device, wherein the further radar signal includes a plurality of frames each comprising a respective sequence of chirps, and wherein the information about the further radar signal indicates at least one of:
- a positioning of sequential chirps with respect to each other for at least one of the plurality of frames;
- and
- a positioning of sequential frames with respect to each other in the further radar signal;
- and
- dynamically adapting at least one parameter of the radar signal based on the information about the further radar signal.
