摘要
A method for estimating direction of arrival, a method for detecting target and an apparatus for estimating direction of arrival are provided to estimate direction of arrival by forming the beam of low level. The method for estimating direction of arrival comprises the antenna element unit(110), and the beam forming unit(120) and arrival calculation unit(130). The antenna element unit receives the wireless electron breach. The antenna element part comprises a plurality of antenna elements the antenna element part forms a plurality of beams in the beam forming unit. The beam forming unit arranges null to beams to the respective fixed phase difference. The beam former comprises the processing unit(121). The processing unit is parallely connected in order to process signal as the respective other condition. The arrival calculation unit measures the sample of the received signal.
