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. 본 발명의 일 실시예에 따른 능동 위상배열 안테나를 이용한 빔 탐색 방법은 행렬 형태로 배열된 복수의 방사 소자를 포함하는 단일 타일형 위상배열 안테나를 이용한 빔 탐색 방법에 있어서, 상기 위상배열 안테나는, 상기 복수의 방사 소자를 포함하고 일 방향으로 배열된 복수의 서브어레이를 포함하고, 상기 서브어레이 별 수신 신호 및 상기 서브어레이 별 빔 계수를 이용하여 상기 서브어레이 별 빔 계수 적용벡터를 산출하는 단계; 상기 서브어레이 별 빔 계수 적용벡터의 절대값 중 최대값에 대응하는 유효 서브어레이의 빔 계수를 초기값으로 결정하는 단계; 및 상기 초기값을 기초로 모노펄스 알고리즘을 수행하여, 상기 위상배열 안테나가 감지하는 빔의 범위인 기준 빔폭보다 큰 확장 빔폭을 획득하는 단계를 포함한다.
