The Application of Pixel Based Imaging to Synthetic Aperture Sonar

Synthetic aperture techniques are commonly applied in Radar processing enabling images to be produced with high, range independent resolution and are now widely proposed for application in Sonar.This paper presents application of Pixel Based imaging to synthetic aperture sonar, a technique successfully applied in forward looking sonar imaging.Four processing schemes are described showing the grating lobe suppression achieved with each scheme.Results from both simulation and test tank experiments are shown.
