Title:
CHANNEL PHASE DETECTION AND CALIBRATION METHOD AND APPARATUS FOR RADAR, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/108380
Kind Code:
A1
Abstract:
Disclosed in the present invention are a channel phase detection and calibration method and apparatus for a radar, and a storage medium. The method comprises: driving a transmitting antenna of a radar to transmit radar signals of multiple channels to a target in a time division manner; acquiring, from a receiving antenna of the radar, echo signals which are reflected by the target and correspond to the channels, and calculating the phase difference between the channels of the radar on the basis of the echo signals; according to the phase difference, performing a phase calibration operation, and a phase consistency detection operation on the basis of the phase relationship between multiplexing array element channels. By means of the technical solution disclosed in the present invention, more accurate estimation results of an azimuth angle and a pitch angle for a detection target can be obtained.
