Towfish Design, Simulation and Control
… such a device in a sensor platform, called a towfish, one may measure turbulent mixing in a vertical swath of the ocean. If the towfish attitude is not precisely regulated, however, the turbulence measurements can be irreversibly corrupted. A two-part tow that includes a depressor weight …

Design and Simulation of a Towed Underwater Vehicle
… tow. A Simulink simulation that models the towfish dynamics was implemented. Through this Simulink simulation a parametric study was conducted to see the effects of sea state, towing speed, center of gravity position, and a PID controller on the towfish dynamics. A detailed static analysis …

Registration and variability of side scan sonar imagery
… is presented in which a side scan sonar towfish images the bottom adjacent to the pier while running along an underwater track which reduces towfish instability. Imagery from this experiment is used to develop a rectification and registration algorithm for side scan sonat images. …
