The 2000-DSS Combined Side Scan Sonar and Sub-Bottom Profiling System is available with a choice of two dual frequency configurations for the side scan sonar: 100/400 kHz and 300/600 kHz. The 2000-DSS uses a high frequency, 2–16 kHz sub-bottom sonar for higher resolution sub-bottom imaging in water...

  • Page 22: Main System Components

    The 2000-DSS Combined Side Scan Sonar and Sub-Bottom Profiling System is composed of two main components: the Rack Mount Topside and the 2000-DSS Tow Vehicle. The Rack Mount Topside is made up of a Topside Processor and a 2000 Digital Telemetry Link installed in a 19-inch rack enclosure, along 1-2.

  • Page 23: 2000 Digital Telemetry Link

    1.2.2 2000 Digital Telemetry Link The 2000 Digital Telemetry Link provides downlink telemetry to the tow vehicle for sonar control and receives uplink side scan and sub bottom data, sensor data and status information from the tow vehicle. It interfaces with the Topside Processor over a 10/100/1000BaseT Ethernet connection and includes tow vehicle and DC power supplies, an asynchronous digital subscriber line (ADSL) modem and an Ethernet switch, all within a single 19-inch 2U chassis.

  • Page 24: 2000-Dss Tow Vehicle

    1-3. IGURE The 2000-DSS Tow Vehicle sub-bottom sonar operates over a frequency range of 2–16 kHz, has a 2000- meter depth rating, and is designed primarily for applications requiring higher resolution sub-bottom imagery. It is hydrodynamically stabilized and includes the sub-bottom transducer and two sub bottom hydrophone arrays mounted under an acoustic baffle.

  • Page 25: Tow Cables

    1.2.4 Tow Cables Both Kevlar reinforced and armored tow cables are available separately, terminated at both ends or just at the tow vehicle end. The tow cables are used to connect to and tow the tow vehicle. A Kevlar reinforced tow cable is shown 1-4.

  • Page 26: Magnetometer

    1.4 Full Spectrum Chirp Technology Overview EdgeTech's Full Spectrum Chirp technology has several distinct advantages over conventional side scan and sub-bottom profiling systems. These benefits include the use of separate sub-bottom acoustic projectors and receivers to enable simultaneous transmission and reception of acoustic signals, high...

  • Page 27: Separate Sub-Bottom Acoustic Projectors And Receivers

    sediment layering and display of along track and across track imagery, reduction of side lobes for minimal reception of undesired echoes, additional processing gain for energy efficiency, and a Gaussian shaped amplitude spectrum of the outgoing pulse to preserve resolution and bandwidth with attenuation. 1.4.1 Separate Sub-Bottom Acoustic Projectors and Receivers The side scan sonar uses a line array of piezoelectric elements to both transmit and receive the acoustic signals, one on the port side of the tow vehicle and one on the starboard side.

  • Page 28: Reduction Of Side Lobes

    As a wavelet with a Gaussian shaped spectrum is attenuated by the sediment, energy is lost but its bandwidth is nearly preserved. Therefore, even after being attenuated, the acoustic pulse has approximately the same resolution as an unattenuated pulse. 2000-DSS COMBINED SONAR 0009335_REV_D...

  • Page 68: Reassembling The Tow Vehicle

    IGURE Calibrating the Compass The compass is calibrated at the EdgeTech manufacturing facility. Should the compass in the towfish lose its calibration for any reason in the field, it may be necessary to recalibrate it. This is accomplished by accessing the embedded Windows installation in the towfish itself via a remote desktop application on the Rack Mount Topside.

  • Page 69: Figure 5-3: Remote Desktop Icon

    Furthermore, it is necessary to physically move the towfish around in different positions for the compass within it to establish the necessary reference points. The support of at least two survey technicians, and a rotating table (as shown in the procedure to follow) or winch for hoisting and rotating the towfish are essential.

The data throughput rate can be checked using EdgeTech supplied utilities at each end of the link The sockBlast application is used to test network throughput between the tow vehicle and the Topside Processor.

    Figure 6-1: sockBlast Window Two copies must be run one on each computer. One serves as the client (topside) and the other as the server (tow vehicle). Since the client connects to the server, the Create Client (topside) address must be the TCP/IP address of the server (tow vehicle) machine, which is 192.9.0.99.
