摘要
A 5G-signal-based DOA fingerprint-based positioning method includes the following steps: dividing an initial area into a number of micro-cells, and estimating angle information of reference points in the divided micro-cells; storing the angle information of the reference point of each micro-cell and position information of the each micro-cell in a fingerprint database, and updating the angle information in the fingerprint database at regular intervals; wherein when there is a target in the initial area, estimating angle information of the target; matching the angle information of the target with the angle information in the fingerprint database to determine a micro-cell where the target is located to obtain position information of the target, so as to locate the target.
