| description | The invention discloses a single base station array positioning method and device based on multi-carrier frequency. The method comprises the following steps of: deploying user equipment and a base station, wherein the base station adopts an antenna array, sends and receives signals on a plurality of frequency points in an allowable communication frequency band, and controls each array element to receive the signals in turn through a switch switching mode; after preprocessing, combining one-dimensional time domain signals of multiple frequency points and multiple antennas into signals with timedomain, frequency domain and space domain three-dimensional characteristics, establishing an objective function according to a combined signal model, optimizing and solving by using a likelihood method and a learning method, and weighting to obtain position parameters such as angles and distances; and performing fusion filtering by combining historical position information and the current position parameters to obtain a |
