    摘要: The present disclosure relates to a method for dynamically controlling ranging power. An electronic device method using ultra-wide band (UWB) communication, according to various embodiments of the present disclosure, comprises the steps of: transmitting an initiation message for initiating UWB ranging; and identifying whether a response message corresponding to the initiation message has been received from another electronic device. The initiation message includes ranging power control request information for dynamic power control with respect to the UWB ranging, and the response message can include ranging power control response information corresponding to the ranging power control request information.

    摘要: Provided are a method and apparatus for calibrating an installation error in a pitch angle of a traffic radar, and a storage medium. The method includes changing the frequency of a traffic radar according to a preset strategy within a preset frequency range; acquiring energy values of echo signals of a preset target at different frequencies in sequence; and in response to determining that the acquired energy values of the echo signals satisfy a preset condition, determining the frequency corresponding to the maximum echo signal energy value as the operating frequency of the traffic radar to calibrate the installation error in the pitch angle of the traffic radar. The preset target is disposed on the ground.

    摘要: A method for antenna calibration is disclosed, the method including driving calibration signals for antenna array beam calibration to an antenna array feeder line in a transceiver front end unit by using one or more directional couplers and/or radio frequency probes, wherein calibration signal paths are integrated inside the transceiver front end unit. Measurements are carried out on the calibration signals, between different antenna combinations inside the antenna array. Based on collected measurement data, calibration information is calculated for each measurement branch of the antenna array by using a mathematical formula. Active antenna array beam calibration is then performed based on the calculated calibration information.
