Problems solved by technology

[0003] In the prior art, when the receiving beam direction is aligned, the average power in multiple receiving beam directions is counted, and then the optimal receiving beam direction is determined. In order to obtain accurate average power, the detection time in each receiving beam direction needs to be sufficient Long, so it takes a long time to align the receiving beam direction

Abstract

An embodiment of the present invention provides an array antenna and a beam alignment method of the array antenna. The array antenna includes a first sub-array, a second sub-array, a first power detector, a second power detector, and a decision device, wherein the The first power detector is connected to the first subarray, the second power detector is connected to the second subarray, the decision unit is connected to the first power detector, and the decision unit is connected to the first power detector. The second power detector is connected, the first power detector is used to detect the power of the output signal of the first subarray, and the second power detector is used to detect the power of the output signal of the second subarray, The decision unit is configured to determine a first alignment direction of the array antenna according to the power of the output signal of the first subarray and the power of the output signal of the second subarray.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an array antenna and a beam alignment method for the array antenna. Background technique [0002] Array antennas are more and more widely used in the microwave field. Each element of the array antenna is equipped with a phase shifter to change the phase of the signal. These phase shifters are usually controlled by electrical signals. For the received signal, the array element will The microwave signal is converted into an electrical signal, and the phase shifter performs phase shift processing on the electrical signal from the array element and sends it to the combiner for combined processing. By changing the phase configuration of these phase shifters, the receiving beam corresponding to the combined signal can be changed direction. [0003] In the prior art, when the receiving beam direction is aligned, the average power in multiple receivin...
