Claim 0:
1. A received signal direction of arrival (DOA) estimation method using generation of virtual received signals, comprising:
generating a preset number of virtual antennas at preset positions of a plurality of actual antennas;
generating received signals received from the virtual antennas; and
generating a DOA estimation value through a DOA estimation algorithm using the received signals received from the virtual antennas and the received signals received from the actual antennas,
wherein the generating of the virtual antennas comprises:
generating a correlation matrix by combining the received signals received from the virtual antennas and the received signals received from the actual antennas, generating an angle estimation spectrum by using the generated correlation matrix, and generating a DOA estimation value.
