Abstract
An object information acquiring apparatus including: a plurality of receiving elements receiving an acoustic wave propagating from an object and converting the acoustic wave into an electrical signal; a delaying unit aligning phases of electrical signals of M (a positive integer) channels outputted from the plurality of receiving elements; an eliminator reducing the electrical signals of the M channels to electrical signals of L channels (L<M); a calculator calculating Nb output signals corresponding to low-frequency components of a complex signal based on the electrical signals outputted from the eliminator; and a signal processor performing beam formation according to adaptive signal processing using output signals outputted from the calculator, where positive integers M, L, and Nb satisfy M>L>=2(Nb−1).
