Abstract
Sea trials of side scan sonar systems have demonstrated a very strong requirement for an automated system to ensure the towed sonar maintains a constant altitude over the sea bottom. This report describes the development of an automated winch control system that achieves this objective. A review of early bottom following techniques is provided, followed by details of the servo-controlled winch and the computer based sea bottom following controller developed by EDRD. Trials results, conclusions, and recommendations for further improvements are presented.
