OVERVIEW

The EdgeTech 2000-TVD (Deep Tow Vehicle) Combined Side Scan Sonar and Sub-Bottom Profiling System
is a combination frequency modulated (FM) dual frequency side scan sonar and a high-resolution FM sub-
bottom profiler that uses EdgeTech’s proprietary Full Spectrum “chirp” technologies to simultaneously
generate both high resolution side scan imagery at longer ranges and high resolution cross sectional
images of the seabed at deeper penetrations than conventional continuous wave (CW) systems.

The 2000-TVD Combined Side Scan Sonar and Sub-Bottom Profiling System is designed to provide 100/400
or 300/600 Hz Side Scan and 1-10 kHz Bottom Scan Sonar in a single pressure housing that is mounted in
a 2000-TVD tow vehicle. The Sub-Bottom receive array is comprised of two individual sensor units that
are externally parallel summed before being connected to the electronics’ pressure housing for
processing. External to the pressure housing is a Kongsberg Mesotech Model 1007D (vendor part number
974-7109000) Altimeter and a Paroscientific 8CB4000-I Depth Sensor.

The two side scan frequencies, along with the sub bottom frequency, are transmitted simultaneously as
linearly swept wide band high energy acoustic pulses (also called "chirp pulses") over a full spectrum
frequency range, and the received echoes are processed into high signal-to-noise (SNR) images which can
be directly displayed as shades of gray or color on a computer monitor and printed on a continuous feed
thermal printer. The data can also be stored in real time onto a large capacity hard drive and archived
onto a DVD.

1.1

Applications

Applications for the 2000-TVD Combined Sonar are many, including:

•

Archeological surveys

•

Geological/geophysical surveys

•

Sediment classification

•

Buried cable and pipeline surveys

•

Dredging and coastal studies

•

Pre/post dredging surveys

•

Scour/erosion investigation

•

Marine construction surveys

1.2

Main System Components

The 2000-TVD system is composed of two main components: a 2000 rack mount topside and a 2000-TVD
towfish. The rack mount topside includes a computer and a STARMUX III digital telemetry link installed in
a 19-inch rack enclosure, along with a keyboard, a trackball, and two LCD monitors. These components
are shown in

. The 2000-TVD towfish is shown in

. Optionally included is a tow cable

up to 6,000 meters in length. (Contact

for cable type versus length).
