Charge Coupled Devices for High-Resolution Sonar Beamforming.

Abstract

Charge coupled devices (CCD'S) were studied under this project to investigate the feasibility of integrating several sonar beamforming functions on a single solidstate 'chip'. These devices will be very important for multi-element high resolution sonar systems because they are compact, reliable, and use little power. Two CCD devices have been fabricated and tested with promising results. One is the Charge Coupled Processer (CCP) which performs several functions needed for narrowband 'holographic' beamforming. A four-input CCP experimental device has tested successfully. The other device,the Cascade Charge Coupled Device (C3D), combines several functions required for a broadband time-delay beamformer. A 20-input device has been tested and has performed beamforming for simulated inputs. Descriptions and experimental results of both devices are discussed in this report. (Author)
