Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 18:
19. The radar device of claim 18, wherein the first communication message comprises first synchronization information indicating a first sending time range, wherein the first sending time range indicates a first time window within which the first vehicle sends the first carrier signal, wherein a second receiving time range and a second sending time range are configured in the radar device, wherein both the second receiving time range and the second sending time range are within a second time gap within which the radar device sends second radar signals in second adjacent periods, wherein a fixed time interval is between the second receiving time range and the second sending time range and is a positive number greater than or equal to zero, wherein the second receiving time range indicates a second time window within which the radar device receives the first carrier signal, wherein the second sending time range indicates a third time window within which the radar device sends a second carrier signal to the first vehicle, wherein the second carrier signal is a response to the first carrier signal, wherein the MCU is configured to adjust the second receiving time range, wherein the second receiving time range is synchronized with the first sending time range, wherein a second duration of the second receiving time range is consistent with a first duration of the first sending time range, wherein the transmit antenna is configured to return the second carrier signal to the first vehicle, wherein the second carrier signal carries a second communication message that is a response to the first communication message.
