  • Page 21: Overview

    S S ECTION 1: OVERVIEW The EdgeTech 4125 Series Dual-frequency Side Scan Sonar System is a frequency-modulated (FM), dual- frequency, side scan sonar that uses EdgeTech’s proprietary Full Spectrum “chirp” technology to generate high-resolution, side scan imagery at longer ranges than conventional continuous-wave (CW) systems.

  • Page 22: Main System Components

    The topside unit includes a laptop computer with Windows 7 and the EdgeTech DISCOVER 4125 Side Scan Sonar software preinstalled. DISCOVER 4125 provides control, storage, and display of the sonar data. The data can be stored in XTF and JSF formats.

  • Page 23: Tow Vehicle

    The 4125-P Portable Topside Processor interfaces with the tow vehicle either over a direct 10/100BaseT connection or, with the additional telemetry option, over a 10BaseT connection that uses very high bit rate digital subscriber line (VDSL) modems. The topside unit also interfaces with a global positioning system (GPS) over a USB to serial or RS-232 serial interface.
  • Page 24 If this happens, the tow vehicle will rotate nose down, and a safety cable, which is attached from the tow point to the rear of the tow vehicle, will pull the tow vehicle over the obstruction or through the snag, stern first. 4125 SIDE SCAN SONAR SYSTEM 0004823_REV_C...
