Shark detection system

摘要

A shark detection system (10) comprising one or more sonar transducers (12) secured to a seabed (18) to detect sonar signals in a region (20) defined by one or more boundary lines. The sonar transducers (12) are directed perpendicular to the boundary line at locations along the boundary line. An equipment housing (14) is connected to the sonar transducers (12) by a signal cable (30) and processing equipment and a communications device are provided within the housing (14). The sonar transducers (12) provide information regarding detected sonar signals via the signal cable (30) to the processing equipment, the processing equipment analyses the received information to determine whether any objects detected match the characteristics of a shark and the communications device transmits a signal to be received by a remote station on determination that a shark has been detected.
