Document Type and Number:
WIPO Patent Application WO/2022/156000
Kind Code:
A1
Abstract:
Provided is a positioning system and method. The positioning system comprises an annular transmitter array (10), an annular receiver array (20), and a positioner (30); the annular transmitter array (10) is used for transmitting a plurality of vortex wave signals to a target object, such that when the plurality of vortex wave signals reach the target object, a plurality of reflected echo signals carrying feedback phase information are generated, wherein the transmission frequencies of the plurality of vortex wave signals are the same, and initial phase information carried by the plurality of vortex wave signals is different; the annular receiver array (20) is used for receiving the reflected echo signals carrying the feedback phase information; and the positioner (30) is used for obtaining target position information of the target object according to the reflected echo signals carrying the feedback phase information.
