Abstract

A method and electronic device for updating a leakage response for leakage cancelation. The electronic device includes a radar transceiver, a memory, and a processor. The processor is configured to determine whether an object is within proximity of and within a field of view of the radar transceiver, obtain a leakage measurement for the radar transceiver in response to determining that no object is proximate to and within the field of view of the radar transceiver, and update the leakage response for leakage cancelation based on the leakage measurement.

Claims (58)

1. An electronic device comprising:

a radar transceiver;

a memory configured to store data; and

a processor operably connected to the radar transceiver, the processor configured to:

determine whether an object is within proximity of and within a field of view of the radar transceiver;

obtain a leakage measurement for the radar transceiver in response to determining that no object is proximate to and within the field of view of the radar transceiver; and

update a leakage response for leakage cancelation based on the leakage measurement.

2. The electronic device of claim 1 , wherein the processor is further configured to:

detect a change in at least one state variable of the electronic device; and

determine whether the object is within the proximity of and within the field of view of the radar transceiver by determining whether the object is within the proximity of and within the field of view of the radar transceiver in response to detecting the change in the at least one state variable.

3. The electronic device of claim 1 , wherein the processor is configured to:

determine whether the object is within the proximity of and within the field of view of the radar transceiver by performing a successful radar-based measurement on a target located outside of the proximity of the radar transceiver, and

obtain the leakage measurement by extracting signals from the successful radar-based measurement corresponding to a set of leakage taps.

4. The electronic device of claim 1 , wherein the processor is configured to:

determine whether the object is within the proximity of and within the field of view of the radar transceiver by confirming that reflected energy from within the proximity of the radar transceiver is proportionate with background levels.

5. The electronic device of claim 1 , wherein the processor is configured to:

determine whether the object is within the proximity of and within the field of view of the radar transceiver further by performing a successful non-radar, sensor-based measurement on a target located outside of the proximity of the radar transceiver, and

obtain the leakage measurement by measuring a leakage signal between a transmitter and a receiver of the radar transceiver.

6. The electronic device of claim 1 , wherein the processor is configured to:

determine whether the object is within the proximity of and within the field of view of the radar transceiver by determining, with a non-radar, proximity sensor that a target is not detected within the proximity of the radar transceiver, and

obtain the leakage measurement by measuring a leakage signal between a transmitter and a receiver of the radar transceiver.

7. The electronic device of claim 1 , wherein the processor is configured to:

determine whether the object is within the proximity of and within the field of view of the radar transceiver by receiving a user input by the electronic device, wherein the user input is correlated with an absence of any objects within the proximity of the radar transceiver, and

obtain the leakage measurement by measuring a leakage signal between a transmitter and a receiver of the radar transceiver.

8. A method for updating a leakage response, the method comprising:

determining, by an electronic device having a radar transceiver, whether an object is within proximity of and within a field of view of the radar transceiver;

obtaining a leakage measurement for the radar transceiver in response to determining that no object is proximate to and within the field of view of the radar transceiver; and

updating the leakage response for leakage cancelation based on the leakage measurement.

9. The method of claim 8 , further comprising detecting a change in at least one state variable of the electronic device; and

wherein determining whether the object is within the proximity of and within the field of view of the radar transceiver comprises determining whether the object is within the proximity of and within the field of view of the radar transceiver in response to detecting the change in the at least one state variable.

10. The method of claim 8 , wherein determining whether the object is within the proximity of and within the field of view of the radar transceiver further comprises performing a successful radar-based measurement on a target located outside of the proximity of the radar transceiver, and

wherein obtaining the leakage measurement further comprises extracting signals from the successful radar-based measurement corresponding to a set of leakage taps.

11. The method of claim 8 , wherein determining whether the object is within the proximity of and within the field of view of the radar transceiver further comprises confirming that reflected energy from within the proximity of the radar transceiver is proportionate with background levels.

12. The method of claim 8 , wherein determining whether the object is within the proximity of and within the field of view of the radar transceiver further comprises performing a successful non-radar, sensor-based measurement on a target located outside of the proximity of the radar transceiver, and

wherein obtaining the leakage measurement further comprises measuring a leakage signal between a transmitter and a receiver of the radar transceiver.

13. The method of claim 8 , wherein determining whether the object is within the proximity of and within the field of view of the radar transceiver further comprises determining, with a non-radar, proximity sensor that a target is not detected within the proximity of the radar transceiver, and
