| Abstract: | This paper studies the realization theory of beamformer with frequency invariant beam pattern of equally spaced linear arrays. It also submits the method to obtain the sub-frequency band weighting matrix for shaping frequency invariant beam pattern by means of window functions, and presents frequency-domain arithmetic model that has used the weighting matrix and affirms its validity through computer simulation. |
