An adaptive beamforming method for an antenna array is provided in which an array output is calculated based on a weight vector <highlight><uline>w</uline></highlight>, which is determined from an eigenvector corresponding to a maximum eigenvaluelambd of a generalized eigenvalue problem consisting of autocovariance matrixes <highlight><duline>R</duline></highlight>xx and <highlight><duline>R</duline></highlight>yy of received signal vectors <highlight><uline>y</uline></highlight> and <highlight><uline>x</uline></highlight>, respectively. The present invention dramatically decreases the total computation requirements by omitting complex matrix operations from the weight vector calculation, thereby making it possible to reduce the weight vector calculation time so as to form the beam pattern for the array antenna system in real time.
