Abstract/Description: In order to image or map targets on an ocean floor, a synthetic aperture sonar platform is moved underwater over the ocean floor. The platform pings or transmits acoustic signals, which reflect off the target back to the receiver. A target image is generated after applying a focusing or a beamforming algorithm on the processed received signal. However the moving platform, when pinging, undergoes motions like yaw, sway, surge, which produce distortions in the final target image. The main objective of this thesis is to geometrically model yaw motion and apply the motion compensation scheme to correct for the yaw motion causing target image distortion. The compensation scheme makes use of phase filtering of the received signals to improve the target image quality. The results obtained, demonstrate effectiveness of the method to compensate for the target image distortion due to yaw motion.
