title: Chirp zeta transform beamforming for three-dimensional acoustic imaging.
abstract: This letter considers the possibility of the generation of three-dimensional acoustic images with a limited computational load by considering the extension of Chirp zeta transform beam forming to the case of planar array and near-field conditions. This extension, with a few innovative solutions, allows for a dramatic reduction in the number of on-line operations over traditional time-domain beamforming.
