Claim 8:
9. The method according to claim 8, 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 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 establishing the equation set with the θ and the ϕ as unknowns, according to the first signals, the second signals, the third signals, 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, and the second difference value is a difference value between the difference between the phase centers after the second change and the difference between the phase centers before the first change;
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, and the second difference value is a difference value between the difference between the phase centers after the second change and the difference between the phase centers after the first change;
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 second change, 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 after the second change.
