Synthetic Aperture Sonar (SAS) performance is limited by motion errors of the towfish. It is necessary to require the towfish moving in a straight line in order to improve the imaging efficiency by Fast Fourier Transformation (FFT). However, the towfish could hardly move along a straight line becaus...
