Abstract
A radar system includes a transmit channel, and a transmit antenna to transmit a signal generated by the transmit channel. The radar system also includes a movement device to cause controlled movement of the transmit antenna. A controller controls the movement device. The controlled movement is used to improve an estimate of azimuth angle to an object detected by the radar system.
Claims20
A radar system, comprising:
- a transmit channel;
- a transmit antenna configured to transmit a signal generated by the transmit channel;
- a movement device configured to cause controlled movement of the transmit antenna;
- and
- a controller configured to control the movement device, wherein the controlled movement is used to improve an estimate of azimuth angle to an object detected by the radar system.
2 more elements
A method of improving angular localization in a radar system, the method comprising:
- coupling a movement device to the radar system to cause controlled movement of a transmit antenna of the radar system that is configured to transmit a signal generated by a transmit channel of the radar system;
- and
- configuring a controller to control the movement device, wherein the controlled movement is used to improve the angular localization including an azimuth angle to an object detected by the radar system.
A vehicle, comprising:
- a radar system comprising:
- a transmit channel;
- a transmit antenna configured to transmit a signal generated by the transmit channel;
- a movement device configured to cause controlled movement of the transmit antenna;
- and
- a controller configured to control the movement device, wherein the controlled movement is used to improve an estimate of azimuth angle to an object detected by the radar system;
- and
- a vehicle controller configured to augment or automate operation of the vehicle based on information from the radar system.
