Abstract: Embodiments of this application disclose a data processing method. The method is used in a multimodal fusion scenario, and the method includes obtaining first data and second data, where modalities of the first data and the second data are different. The method also includes obtaining a first feature set of the first data and a second feature set of the second data, and replacing a first target feature in the first feature set with a second target feature in the second feature set, to obtain a third feature set, where the second target feature corresponds to the first target feature. The method further includes obtaining a data feature based on the third feature set and the second feature set, where the data feature is used to implement a computer vision task.

Abstract: This application provides a signal processing method and apparatus, may be applied to the field of automatic driving or intelligent driving, in particular to millimeter wave radar target detection. The method includes: A detection apparatus receives at least one first signal corresponding to a first transmit antenna, and performs beamforming processing on the at least one first signal to generate a first beam; and determines information about the first target based on the first beam and a phase of a second beam corresponding to at least one second signal. By this solution, the detection apparatus such as a single-input multiple-output SIMO radar, a multiple-input multiple-output MIMO radar or a cooperative radar, may determine, based on a phase of the first beam and the phase of the second beam, a Doppler phase difference, and determine, based on the Doppler phase difference, the information about the first target.
