Method and system for synthetic aperture sonar
The Journal of the Acoustical Society of America, 2008A method and system for synthetic aperture sonar provide improved position estimates of a receive array as in moves through a body of water.

Circular synthetic aperture sonar design
Europe Oceans 2005, 2005Medical imaging enjoys a reputation of applying multi-aspect sensing to construct internal maps of patients. The CAT scan evokes a concept of an X-ray probe moving around the patient; the multi-aspect data is processed to construct images of the areas of interest.

Modified Algorithm for Synthetic Aperture Sonar
OCEANS 2008 - MTS/IEEE Kobe Techno-Ocean, 2008It is hard to negate the effects of ocean waves on a synthetic aperture sonar that has to operate in the ocean, and many efforts against the ocean waves had been taken. One of the effort is motion compensation by calculating phase errors with computer.

The prehistory of synthetic aperture sonar
The Journal of the Acoustical Society of America, 1997It is necessary to go back to 1958 (A.D.) and the summer of 1959. The concept of using recorded data obtained from a single moving element to provide a ‘‘memorized array’’ instead of the multiple-element physical array, was offered to ONR (Aubrey Pryce), whose reaction will be described.

Results of synthetic aperture sonar experiments
OCEANS 2000 MTS/IEEE Conference and Exhibition. Conference Proceedings (Cat. No.00CH37158), 2002Results are presented from synthetic aperture sonar (SAS) experiments with three different test systems: one oriented toward mine detection; one toward buried UXO detection; and one toward buried cable detection. The first two systems share hydrophone arrays of 32-10-cm long elements.

A short history of synthetic aperture sonar
IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998The fundamental theory that underpins any synthetic aperture sonar (SAS) is the same as that developed for synthetic aperture radar (SAR). However, the slow speed of propagation and higher attenuation of acoustic waves in water provides for some significant practical differences.

Interferometric transmission synthetic aperture sonar
Seventh International Conference on Electronic Engineering in Oceanography - Technology Transfer from Research to Industry, 1997Synthetic aperture has the potential for an order of magnitude improvement in the cross-range resolution of side-scan imaging sonars. However, two problems have up to now prevented the operational deployment of such systems in the ocean. The first relates to the focusing of the array despite platform wander and sound speed fluctuations, which lead to ...

Holographic Synthetic Aperture Sonar System
1974As one of the ultrasonic imaging techniques, a sonar system is widely used in oceanography to measure the depth of bottom and to locate schools of fish or other submerged objects. In the conventional sonar system which uses the ultrasonic pulse-echo method, the resolution limit of the object in range, the longitudinal resolution, is determined by VT/2;
