1 INTRODUCTION
The 4200-FS Side Scan Sonar combines EdgeTech’s Full Spectrum Chirp and Multi-Pulse
technologies to provide a unique dual mode of operation system.
The surveyor may run the 4200-FS system in either of the following software selectable
modes:
•
High Definition Mode (HDM):
Conventional simultaneous dual frequency mode of
operation using extra long arrays for superior resolution.
•
High Speed Mode (HSM):
Dual pulse operation for speed up to 10 knots, while
meeting NOAA and IHO requirements for ‘hits on target’.
When operating at the High Speed Mode (HSM) the surveyor can select either of the
operational frequencies, namely 410 kHz for up to 200 meter per side coverage or 120 kHz
for up to 500 meter per side coverage.
The 4200-FS uses a variant of EdgeTech’s deep water proven StarMux® Digital Telemetry
System to link the topside to the towfish using a single coaxial cable up to 6000m long.
The 4200-FS system comprises the following major components:
•
4200 Towfish
•
Option 1: 4200-FS Processor (19" rack mount PC, - Model 566 processor)
•
Option 2: 4200-FS Portable Processor (Waterproof carry case – Model 566P
processor)
•
100 feet (30 m) Test Tow cable
•
Tow cable (as per order)
