Features
The system consists of the vehicle, fiber-optic tow cable, handling system, generator operations van and a maintenance van. Navigation is accomplished by using algorithms incorporating the amount of cable in the water and the depth indication from the pressure sensor. Electrical power from the support platform can be used for the system if it is compatible; otherwise a generator provides the power.
SWISS is a dual frequency (100/500 kHz) towed side-scan sonar system mounted inside a torpedo shaped tow body. The sonar is towed behind a vessel at slow speeds, generally from 1-5 knots depending on the required depth. Sonar signals are processed producing both an analog and digital display in order to identify potential targets. The low frequency is primarily used for searching for large objects or at long ranges, while the higher frequency provides extremely fine details and operates at shorter ranges.
