Title:
SIGNAL ORIENTATION METHOD AND APPARATUS, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/111516
Kind Code:
A1
Abstract:
A signal orientation method and apparatus, and a computer-readable storage medium. The method comprises: acquiring, by means of a sensor array, multiple signals to be oriented (step 201); for each preset direction among multiple preset directions, performing the following steps (step 202): on the basis of each preset direction, determining a first signal feature of the multiple signals (a), on the basis of the opposite direction of each preset direction, determining a second signal feature of the multiple signals (b), and determining a difference value of the first signal feature and the second signal feature (c); comparing the size of the difference values corresponding to the multiple preset directions, and determining the preset direction corresponding to the largest difference value as a target signal direction (step 203). The present method can reduce orientation errors caused by sensor response distortion, achieve good adaptive anti-noise capability, and achieve more accurate signal orientation.
