Abstract : The present invention relates to a system and a method for determining the bearing of an object located at a distance from a reference point. A plurality of sensors are mounted to a body to detect signals emanating from the object and to convert those signals into electrical signals. The electrical signals are then processed to determine the bearing of the object from the body. The system can include a float with the body suspended from said float immersed in a fluid medium. A method for processing the electrical signals and generating the bearing information is also described.
