A Review of Advances in Synthetic Aperture Sonar Imaging Algorithms

Abstract: Synthetic aperture techniques use coherent addition over many pings to create an aperture whose extent can be increased with range to maintain a constant along-track resolution. This paper is a review, dealing the past works in, and the recent status of, active Synthetic Aperture Sonar (SAS), covering the early developments in SAS. By constructing the SAS, it can eliminate the huge hardware requirement. A new image recovery method is proposed using the compressive sensing. The proposed method deals with a reconstruction of SAS image using the sparse recovery method. The number of samples for recovery is low when using Compressive Sensing.
