Abstract

A beam signal tracking method, device and system. The method includes: acquiring the Doppler frequency shift of the received beam signal, determining the change speed of the Doppler frequency shift of the received beam signal according to the Doppler frequency shift (S10); changing the Doppler frequency shift according to the Doppler frequency shift The speed determines the scanning speed and the scanning angle step of the receiving beam signal (S20); according to the scanning speed and the scanning angle step, the receiving beam is scanned, and the beam angle when the receiving beam signal is aligned with the transmitting beam signal is determined (S30) ; Determine the phase configuration information of the phase shifter according to the beam angle when the receiving beam signal is aligned with the transmitting beam signal (S40); configure the phase shifter according to the phase configuration information of the phase shifter so that the receiving beam signal Align with transmit beam signal (S50).

Description

technical field [0001] The present invention relates to communication technology, in particular to a beam signal tracking method, device and system. Background technique [0002] In the phased microwave communication technology, the phase change is mainly used to realize the movement or scanning of the antenna beam pointing in space. Phased arrays are composed of antenna arrays, phase shifters, feeder networks, and corresponding control circuits. The antenna arrays are composed of multiple antenna units, and each antenna unit is equipped with a phase shifter at the rear end. Used to change the signal phase of the antenna unit. The phase configuration of the phase shifter is controlled by the corresponding control circuit to form a specific directional transmit beam or receive beam. The transmitting device Tx uses a phased array to complete directional transmission, and correspondingly, the receiving device Rx also uses a phased array to complete directional reception. The...
