Electronically stabilized beam former system

Abstract From the Canadian patent

Abstract of the Disclosure, A sonar system comprising a curved transducer array typically in the form of a cylinder, in which the transducer elements are arranged in geometrically similar configurations on each of a plurality of planes having symmetry about a common axis. In the presence of an incident beam of radiant energy, the transducer elements are excited by signals having values of delay which vary from transducer to transducer in a regular pattern resulting from the symmetry of the array. This permits the utilization of a relatively small memory for the storing of delay values as a function of the bearing and tilt of the center line of a receiving beam relative to the axis of the …
