| Abstract: | Synthetic aperture sonar (SAS) is a technique of high resolution underwater imaging. Synthetic large aperture is formed based on small aperture array and its motion, and high resolution image is hence obtained by means of beam forming for large aperture array. Principle, characteristics, problem and history of SAS are presented in the paper. Recent developments and trend are analyzed as well. |

| Keywords: | synthetic aperture sonar (SAS) imaging algorithm motion compensation |
