Product Name:PDDS-X


PDDS-X is a portable sonar system capable of detecting potential underwater threats like divers and diver delivery vehicles in shallow waters. The system alerts the operator to confirm the type of threat so that effective countermeasures can be initiated in time. The system can be deployed either outboard a ship or at any location in a harbour, typically beside a wall, pier or at the sea bottom. The system consists of two parts, an underwater unit and a shore unit, interconnected by water blocked cable carrying data and power supply lines. The underwater unit is a sonar head consisting of transducer arrays, transmitter and front-end receiver electronics hardware. The shore unit consists of the processing and display units, data recorder and power supply. As an auto-alert system, PDDS-X performs detection, tracking and classification of divers or diver-like targets automatically and alerts the operator accordingly. The target information provided by the system include:

(i) Target position (range and bearing) and
(ii) Target dynamics (speed and course).
