Assignee: HYUNDAI MOBIS CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 6:
7. A received signal DOA estimation apparatus using generation of virtual received signals, comprising:
a Uniform Linear Array (ULA) reception antenna comprising a plurality of actual antennas;
a reception unit configured to extract a predetermined signal from received signals received through the actual antennas of the ULA reception antenna and convert the extracted signal into a digital signal; and
a signal processing unit configured to receive the digital signal from the reception unit, generate received signals received from a preset number of virtual antennas disposed at preset positions, and generate a DOA estimation value through a DOA estimation algorithm by using the received signals received from the actual antennas and the received signals received from the virtual antennas,
wherein the signal processing unit is configured to generate a correlation matrix by combining the received signals received from the virtual antennas and the received signals received from the actual antennas, generate an angle estimation spectrum by using the generated correlation matrix, and generate a DOA estimation value.
