Compressive Underwater Sonar Imaging with Synthetic Aperture Processing [PDF]
Remote Sensing, 2021 Synthetic aperture sonar (SAS) is a technique that acquires an underwater image by synthesizing the signal received by the sonar as it moves. By forming a synthetic aperture, the sonar overcomes physical limitations and shows superior resolution when compared with use of a side-scan sonar, which is another technique for obtaining underwater images ...
