Abstract:
This material was presented as a paper to the 2nd International Symposium of Acoustical Holography sponsored by McDonnell-Douglas at Huntington Beach, California, March 6, 1969. The possible application of acoustical holography to conventional sonar problems is considered, in which acoustical fields are recorded in optical form and optically reconstructed. Also considered are other related coherent optical techniques for processing sonar data. The similarities, differences, and limitations of the various systems are described. Comparisons are made which include: ranging and lateral resolution, aperture size, number of array elements, bandwidth, center frequency, and the possibility of signal averaging to improve image quality.
