Abstract
A beam signal tracking method, device, and system, where the method includes obtaining a Doppler frequency shift of a receive-beam signal, determining a Doppler frequency shift change speed of the receive-beam signal according to the Doppler frequency shift, determining a scanning speed and a scanning angle step size of the receive-beam signal according to the Doppler frequency shift change speed, scanning the receive-beam signal according to the scanning speed and the scanning angle step size, determining a beam angle that is formed when the receive-beam signal is aligned with a transmit-beam signal, determining phase configuration information of a phase shifter according to the beam angle that is formed when the receive-beam signal is aligned with the transmit-beam signal, and configuring the phase shifter according to the phase configuration information of the phase shifter such that the receive-beam signal is aligned with the transmit-beam signal.
