Claim 18:
19. The method according to claim 4, wherein establishing the equation set with the θ and the ϕ as unknowns comprises:
determining a first difference value and a second difference value, according to 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, and 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, respectively; and establishing the equation set with the θ and the ϕ as unknowns, according to the first signals and the second signals received by the first group of the analog subarrays, the first signals and the second signals received by the second group of the analog subarrays, the first difference value and the second difference value;
wherein, the first difference value is a difference value between the difference between the phase centers after the first change and the difference between the phase centers before the first change, of the first group of the analog subarrays, and the second difference value is a difference value between the difference between the phase centers after the first change and the difference between the phase centers before the first change, of the second group of the analog subarrays;
or, the first difference value is a difference value between the difference between the phase centers before the first change and the difference between the phase centers after the first change, of the first group of the analog subarrays, and the second difference value is a difference value between the difference between the phase centers before the first change and the difference between the phase centers after the first change, of the second group of the analog subarrays.
