Claim 17:
18. The method according to claim 12, wherein estimating the DOA of the receiving signal comprises:
establishing an equation set with θ and ϕ as unknowns, 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; wherein the θ is a zenith angle of the DOA, the ϕ is an azimuth of the DOA; and
obtaining the θ and the ϕ by solving the equation set.
