Description

The New Edgetech 4200-FS Side Scan System combines Edgetech's Full Specturm and MultiPulse technologies into one unit providing a unique advantage over conventional dual frequency 100/500 kHz side scan systems. It has two software modes of operation: High Definition Mode and High Speed Mode.

· High Definition Mode (HDM) - conventional mode operation with extra long array (90 cm) for superior resolution; excellent tool for Mine Countermeasures ( MCM's ).

· High Speed Mode (HSM) - dual pulse operation for speeds up to 10 knots, while meeting NOAA and IHO requirements for "hits on target" compared to conventional systems at 4 knots.

The 90 cm array configuration for these two modes of operation is dynamically reconfigured by the system to suit the user's immediate application. Real time selection of the 2 modes allows the user to choose the mode best suited to his task at hand. The 4200-FS uses EdgeTech's Full-Spectrum chirp technology to deliver wide band, high energy transmit pulses, coupled with high-resolution and superb signal to noise ratio (SNR) echo data. The system employs wide band, low noise front end electronics which reduce system induced phase errors and drift to negligible levels. The sonar data is also available as a complex, fully coherent data set suitable for advanced user applied post processing. The 4200-FS Side Scan System offers simultaneous dual frequency operation in high definition mode and is designed to allow efficient integration of other optional sensors. The Edgetech telemetry link allows the sonar signals that are digitized in the tow fish to be transmitted over the long coaxial cable (6000m) with no loss of signal quality. The 4200-FS sets new standards in the industry for seafloor mapping by integrating key performance and safety features, the dual mode feature along with EdgeTech's Secondary Recovery System, Standard Heading, Pitch & Roll, optional Depth and acoustic responder for accurate towing positioning.
