Claim 16:
17. The method according to claim 12, wherein estimating the DOA of the receiving signal comprises:
determining an objective function, according to the first signals and the second signals received by the first group of the analog subarrays, the difference between the phase centers before change and the difference between the phase centers after change of the first group of the analog subarrays, the first signals and the second signals received by the second group of the analog subarrays, the difference between the phase centers before change and the difference between the phase centers after change of the second group of the analog subarrays; and
traversing all desirable DOAs to obtain a value of the objective function corresponding to each of the desirable DOAs, and take a DOA with a smallest value of the objective function as the estimated DOA.
