DESCRIPTION
|
The 4200 Series utilizes EdgeTech’s Full
Spectrum CHIRP technology to provide crisp, high resolution imagery
at longer ranges than conventional side scan systems. The 4200
Series comes available in two different versions; the 4200-SP
and 4200-MP. The 4200-SP acts as a traditional side scan
system whereas the 4200-MP is a dual mode system with an added
High Speed Mode (HSM) of operation.
The two software selectable modes of operation
for the 4200-MP are as follows:
• High Definition Mode (HDM) – conventional
dual simultaneous frequency operation with extra long array for
superior resolution; excellent tool for Mine Countermeasures (MCM).
• High Speed Mode (HSM) – utilizes EdgeTech's Multi-Pulse
technology which places two pulses into the water rather than
one. This allows the system to be towed at speeds of up to 10
knots while meeting NOAA and IHO-44 requirements for minimum 3
pings on a 1 meter target compared to conventional systems at
only 4 knots.
The array configuration for the 4200-MP's 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 Series utilizes EdgeTech's Full Spectrum
CHIRP technology to deliver wide band, high energy transmit pulses,
coupled with high resolution and superb signal to noise ratio
echo data. The systems 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 Series is also designed to allow efficient
integration of other optional sensors. The EdgeTech telemetry
link allows the sonar signals that are digitized in the towfish
to be transmitted over long coaxial cable lengths with no loss
of signal quality.
|
The 4200 Series offers two towfish options based
upon the user’s desired applications; a stainless steel
or lightweight aluminum version. The stainless steel towfish is
ideal for deeper water operation of up to 2000 meters and the
lightweight aluminum towfish for shallower water operation of
depths up to 500 meters.
Along with the choice of towfish, the 4200 Series
also offers three different topside processor options which again
allows the user to customize the system to best suit his needs.
All of the topside processors come installed with EdgeTech’s
DISCOVER software, which serves as the control and data acquisition
sub-system for display, storage and printing of sonar data. You
also have the option of configuring the system for third-party
interface and or utilizing your own PC / laptop.
The EdgeTech Model 4200 Topside Processor is
a standard 19” rack mountable topside that is ideal to use
on larger vessels or when portability is not a main concern. In
this configuration, all of the electronics are housed within a
19” rack mounted Windows© based PC System and the data
is displayed on a high resolution flat screen color monitor.
The EdgeTech Model 4200-P Topside Processor
is a portable unit that is ideal for smaller ships or when operating
outside of a protected area. All of the electronics are mounted
within a waterproof “suitcase-style” housing and the
data is displayed on a splashproof laptop computer via a wired
or wireless Ethernet connection.
For customers who would prefer to use their
own 3rd party topside processor, EdgeTech offers the 701-DL (Digital
Link) which acts as the interface between the 4200 Series towfish
and the display and acquisition software. With this option the
user supplies the PC and runs the 4200 System using EdgeTech’s
DISCOVER software.
The 4200 Series 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, Magnetometer interface and Acoustic responder for accurate
towing positioning at a price which is commercially sensitive.
