Claim 1:
2. The method according to claim 1, wherein before estimating the DOA of the receiving signal, the method further comprises:
keeping the beam directions of the receiving beams of the two analog subarrays unchanged, performing a third change of the difference between the phase centers of the two analog subarrays, and acquiring fourth signals received by the two analog subarrays and the difference between the phase centers after the third change of the two analog subarrays;
wherein estimating the DOA of the receiving signal comprises:
estimating the DOA of the receiving signal, according to the first signals, the second signals, the third signals and the fourth 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, the difference between the phase centers after the second change and the difference between the phase centers after the third change.
