An angle estimating method applied in a radar system includes receiving a first signal and a second signal reflected from a target object via a first antenna and a second antenna; obtaining a first phase difference and at least one virtual phase difference, where the first phase difference is a phase difference between the first antenna and the second antenna; and obtaining a direction of arrival (DOA) of the target object according to the first phase difference and the at least one virtual phase difference.
