Title: CCD Signal processor
Abstract:
Apparatus for forming one or more sonar beams in response to acoustic energy received by a transducer array. To minimize volume utilization, a plurality of CCD's are formed on an integrated circuit chip with the CCD's being of progressively smaller length. Half of the CCD array is folded over to match the other half so that each CCD has an opposing CCD with both CCD's propagating a signal toward a common output diode. By providing one integrated circuit chip for each desired beam with appropriately different clocking frequencies multiple beams may be formed, and with the provision of a variable clocking frequency, one or more beams may be steered. Transversal filter operations may also be performed by the apparatus.
