description | An embodiment of the present invention provides a beam search method using an active phased array antenna, in which the beam search method uses a single tile-type phased array antenna including a plurality of radiating elements arranged in a matrix form, and the phased array antenna includes a plurality of sub-arrays including the plurality of radiating elements and arranged in one direction, wherein the method includes the steps of: calculating a beam coefficient application vector for each of the sub-arrays by using a received signal for each of the sub-arrays and a beam coefficient for each of the sub-arrays; determining, as an initial value, a beam coefficient of an effective sub-array corresponding to a maximum value from among absolute values of beam coefficient application vectors for each of the sub-arrays; and performing a mono-pulse algorithm based on the initial value to obtain an extended beamwidth greater than a reference beamwidth, which is a range of a beam detected by the phased array antenna. A precise omnidirectional beam search can be performed.
