An antenna alignment method and system

Abstract

An embodiment of the present invention provides an antenna alignment method. The first device has N AT transmit beams, N AR receiving beams, the second device has N BT transmit beams, N BR receive beams, the first device transmits signals to the second device according to the first cycle, and traverses N according to the third beam pattern AT In the switching of a transmission beam, the transmission beam of the signal transmitted by the first device in the same first cycle remains unchanged; the second device receives the signal from the first device according to the first cycle, and traverses N according to the fourth beam pattern BR Switching of receiving beams, the receiving beams of the second device receiving signals in the same first period remain unchanged, and each receiving beam can receive signals from the first device N AT The signal of the transmitting beam; the second device counts the power of the received signal in each first period, and obtains the power of the received signal corresponding to each receiving beam according to the fourth beam pattern, and obtains the maximum power of the received signal corresponding to the S receiving beam ; The beam with the highest power of the received signal of the fixed receiving beam of the second device is the receiving beam.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna alignment method and system. Background technique [0002] In a microwave device equipped with an electrically adjustable array antenna, each element of the array antenna has a phase shifter that changes the phase of the signal, and these phase shifters are controlled by electrical signals to form the desired radiation beam on the array antenna . When such a microwave device communicates, it is necessary to simultaneously align the beams of the transmitting antenna and the beams of the receiving antenna with the microwave device at the opposite end. [0003] In the prior art, the beam alignment of the local microwave device needs to be detected and judged by the peer microwave device, and the judgment information is sent back to the local microwave device. However, before the beam is aligned, the communication link cannot work norm...

AI Technical Summary

Problems solved by technology

However, before the beam is aligned, the communication link cannot work normally, and an additional feedback channel needs to be built, which is costly and difficult to implement
