Abstract
Various aspects may include an apparatus for radar calibration including a radar control system and a first radar antenna and a second radar antenna, one on the inside of a device housing area and the other on the outside of a device housing area. Both antennae may be mounted to the device housing area. By transmitting a signal from one antenna to the other, various aspects of the signal may be measured by the radar control system in order to determine a calibration parameter for radar calibration.
Claims30
An apparatus for radar calibration, comprising:
- an external radar antenna assembly, wherein the external radar antenna assembly is operably configured to transmit or receive radar signals while positioned outside of a device housing area;
- an internal radar antenna assembly, wherein the internal radar antenna assembly is positioned inside of the device housing area;
- and
- a radar control system;
- wherein the radar control system is operably configured to:
- a) send a first radar signal to the external radar antenna assembly and receive the first radar signal via the internal radar antenna assembly, or
- b) send a second radar signal to the internal radar antenna assembly and receive the second radar signal via the external radar antenna assembly;
- wherein the radar control system is further operably configured to adjust a radar calibration parameter on the basis of the received first radar signal or the received second radar signal.
A method for radar calibration, comprising:
- a) sending, from a radar control system, a first radar signal from an internal radar antenna assembly positioned inside a device housing area to an external radar antenna assembly positioned outside the device housing area and receiving the first radar signal via the internal radar antenna assembly, or
- b) sending, from the radar control system, a second radar signal to the internal radar antenna assembly and receiving the second radar signal via the external radar antenna assembly;
- and
- adjusting, with the radar control system, a radar calibration parameter on the basis of the received first radar signal or the received second radar signal.
A system for radar calibration, comprising:
- a) means for sending a first radar signal from an internal radar antenna assembly positioned inside a device housing area to an external radar antenna assembly positioned outside the device housing area and means for receiving the first radar signal via the internal radar antenna assembly, or
- b) means for sending a second radar signal to the internal radar antenna assembly and means for receiving the second radar signal via the external radar antenna assembly;
- and
- means for adjusting a radar calibration parameter on the basis of the received first radar signal or the received second radar signal.
A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause:
- a) a radar control system to send a first radar signal from an internal radar antenna assembly positioned inside a device housing area to an external radar antenna assembly positioned outside the device housing area and to receive the first radar signal via the internal radar antenna assembly, or
- b) the radar control system to send a second radar signal to the internal radar antenna assembly and to receive the second radar signal via the external radar antenna assembly;
- and
- the radar control system to adjust a radar calibration parameter on the basis of the received first radar signal or the received second radar signal.
