- Abstract
- One possible approach to remotely controlled minehunting is to tow a sonar towfish behind an unmanned drone. Measurements of the attitude, depth, and accelerations of the towfish are reported, and these values are compared with the stability criteria the towfish must satisfy for the production of acceptable sonar images. The drone was a Dolphin, a snorkelling submersible developed and manufactured by International Submarine Engineering Ltd., Port Coquitlam, BC. The trial was conducted mostly in calm seas; experiments are described in which the drone was made to yaw, pitch, or roll under operator control. Simple physical models for the observed behaviour are given. Runs in modest waves are also described.
