Abstract : The patent describes an improved method and apparatus for processing electronic signals for use in establishing an improved image display. It includes storing the electronic and acoustic response of all the detectors in response to impingement thereon by a plane wave-front as stored in a memory. In the operational environment, these stored signals are combined with the transducer response and the signals are combined in such a fashion as to compensate for spatial nonuniformities.
