Abstract:
A method for determining a DOA (Direction of Arrival) comprises the following steps: (a) providing at least two antennas arranged with a squint angle; (b) producing at least two base beams between two adjacent base beams; (c) every two virtual beams of the multiple virtual beams which cross together at a specific angle are define to a virtual beam set; (d) synthesizing the two virtual beams of each one of the virtual beam sets to be a monopulse; and (e) determining the DOA of the object according to comparison between magnitude of demodulated signals corresponding to the monopulses. A device for estimating a DOA is also disclosed.
