Title:
ROTATIONAL SPEED MEASUREMENT METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/155997
Kind Code:
A1
Abstract:
A rotational speed measurement method, apparatus and a device, and a storage medium. The method comprises: transmitting a vortex sound wave to an underwater rotating target, and collecting an echo signal generated after the vortex sound wave is scattered by the underwater rotating target (5); analyzing the echo signal by means of pre-set analysis, so as to obtain a spectral offset of the underwater rotating target; and on the basis of the spectral offset, calculating rotational speed information of the underwater rotating target (5).
