Claim 10:
11. A device for realizing beam alignment, comprising a processor, and a computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform a method for realizing the beam alignment, comprising:
in response to a reception of first signals with effective signal strengths through two analog subarrays with a same polarization mode by adopting receiving beams having a same beam direction, acquiring the first signals received by the two analog subarrays, and a difference between phase centers of the two analog subarrays;
keeping the beam directions of the receiving beams of the two analog subarrays unchanged, performing a first change of the difference between the phase centers of the two analog subarrays, and acquiring second signals received by the two analog subarrays and the difference between the phase centers after the first change of the two analog subarrays;
keeping the beam directions of the receiving beams of the two analog subarrays unchanged, performing a second change of the difference between the phase centers of the two analog subarrays, and acquiring third signals received by the two analog subarrays and the difference between the phase centers after the second change of the two analog subarrays; and
estimating a Direction Of Arrival (DOA) of a receiving signal, according to the first signals, the second signals and the third signals received by the two analog subarrays, the difference between the phase centers before the first change, the difference between the phase centers after the first change and the difference between the phase centers after the second change; and directing a center of a receiving beam to the estimated DOA.
