Title:
SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/129581
Kind Code:
A1
Abstract:
Disclosed are a signal processing method and apparatus, wherein same can be applied to the field of automatic driving or intelligent driving, and relate in particular to target detection by means of a millimeter-wave radar. The method comprises: a detection apparatus receiving at least one first signal corresponding to a first transmission antenna, and executing beamforming processing on the at least one first signal to generate a first beam; and according to the phase of the first beam and the phase of a second beam corresponding to at least one second signal, determining information of a first target. By means of the solution, a detection apparatus, such as a signal-input multiple-output (SIMO) radar, a multiple-input multiple-output (MIMO) radar or a collaborative radar, can determine a Doppler phase difference according to the phases of a first beam and the phase of a second beam, and can then determine information of a first target according to the Doppler phase difference. Therefore, the effect of a Doppler phase difference on target detection by means of a detection apparatus can be reduced, and the accuracy of target detection by means of the detection apparatus can be improved.
