SECTION 1: OVERVIEW

The EdgeTech 6205s is a fully integrated Swath Bathymetry and Dual Frequency Side Scan Sonar System that uses multiple receive elements, and one discrete transmit element, to produces real time, high resolution, side scan imagery, and three-dimensional maps of the seafloor. The 6205s overcomes the limitations of Multi Beam Echo Sounders (MBES) and Interferometric systems in shallow water by using EdgeTech’s unique Multi-Phase Echo Sounder (MPES) technology. This Hybrid approach combines both Beamforming and Phase Discrimination techniques to determine each sounding along the seafloor. With the integration of EdgeTech’s Full Spectrum® CHIRP technology, the 6205s exceeds IHO SP-44, NOAA, and USACE specifications for Feature Detection and Bathymetric Point Data Uncertainty.
EdgeTech’s MPES technology enables the 6205s to produce wider and cleaner swath (over 200º) than current technologies, resulting in superior coverage enabling faster and safer survey completion. At the same time, the 6205s rejects multipath effects, reverberation, and acoustic noise commonly encountered in shallow water environments.
The 6205s provides Dual Frequency Side Scan Sonar, operating at 230/550 kHz, 550/850kHz or 550/1600 kHz, while the Side Scan imagery is collected simultaneously on both frequencies. The Bathymetry operates at either 230kHz or 550kHz.
Additionally, EdgeTech’s latest 2205 Electronics and Modular Arrays are utilized in the 6205s, resulting in an extremely lightweight design, which is required for shallow water applications and vessels of opportunity. The 2205 electronics and arrays are mounted onto a streamline body that is deployed over­the-bow or side of a survey vessel. Sonar data is transferred from the transceiver to the processing unit on board via an Ethernet network interface.
The standard configuration for the 6205s includes an integrated Sound Velocity Sensor, and interfaces to most Third-Party acquisition and processing software packages, and to standard DGPS/RTK systems, Altimeters, GPS, MRU, SVP, Gyros, and INS—altogether offering a powerful and versatile acquisition system that is suitable for many different applications.
The 6205s has a variety of features, including:
Next generation MPES technology
Unrivaled Swath coverage in shallow water, when compared to other single head systems
• Swath sectors of up to 200°
Co-registered Dual Frequency Side Scan and Single Frequency Bathymetry
• Superior multipath rejection
IHO SP-44 Special Order compliant
• Equidistant and Equiangle output options
Comes with EdgeTech’s Discover Bathymetric Sonar Control Software
Motion tolerant Side Scan
Universal MRU Mounting Plate
Field swappable Transducers (Bathymetric Electronics can swap between 230khz or 520khz)
SECTION 2: SYSTEM DESCRIPTION 1-2

1.1 Applications

The 6205s next generation Swath Bathymetry & Side Scan Sonar has many potential applications, a few of which include:
• Shallow Water Hydrographic Surveys
• Benthic Habitat Mapping
• Nautical Charting
• Military Rapid Environmental Assessments (REA)
• Route Surveys
• Dredging Operations
• Marine Debris Search
• Port & Harbor Security

1.2 Options

The 6205s is available in several standard frequency configurations:
• 230 / 550 kHz Dual Frequency Side Scan with 230 kHz Bathymetry Data
• 230 / 550 kHz Dual Frequency Side Scan with 550 kHz Bathymetry Data
• 550 / 850 kHz Dual Frequency Side Scan with 550 kHz Bathymetry Data
550 / 1600 kHz Dual Frequency Side Scan with 550 kHz Bathymetry Data
The modular design of the 6205s allows for multi-frequency bathymetry options in a single sonar head. The field exchangeable array capability allows both shallow and deep-water operations but is only available with 230 / 550 kHz Side Scan systems. The difference between the different frequency arrays is identified by color. Refer to F
IGURE 3-9 for frequency differentiations by color.

SECTION 2: SYSTEM DESCRIPTION

The complete 6205s system consists of a Swath Bathymetry and Side Scan Sonar Head and a Topside Interface Box. This section describes the 6205s System main components and lists its specifications.

2.1 The 6205s Sonar Head

The 6205s Swath Bathymetry and Side Scan Sonar Head is available in a variety of frequency options:
• 230 / 550 kHz Dual Frequency Side Scan with 230 kHz Bathymetry Data
• 230 / 550 kHz Dual Frequency Side Scan with 550 kHz Bathymetry Data
550 / 850 kHz Dual Frequency Side Scan with 550 kHz Bathymetry Data
• 550 / 1600 kHz Dual Frequency Side Scan with 550 kHz Bathymetry Data
The frequency sets listed above were chosen to provide optimum results for any given water depth up to 200m (660ft) below the transducer. The 6205s is for water depths between 5m – 50m (15ft – 164ft). Optimal Frequency depends on survey requirements.
To mitigate frequency tradeoffs, EdgeTech has designed the 6205s Sonar Head with Field Exchangeable Arrays whereby the Bathymetry frequency can be switched from the low frequency channel to the high frequency channel or vice versa. However, this feature only exists on the 230 kHz/550 kHz models.
The 6205s Swath Bathymetry and Side Scan Sonar Head comes standard with a Sonar Processor, Port and Starboard Sonar Arrays, a Sound Velocity Sensor (SVS), and Housing. These components are demonstrated

2.1.1 Mounting Plate

The 6205s Mounting Plate is made of stainless steel and was designed with a variable bolt pattern to secure the system to several different deployment mechanisms, thereby cutting back on installation and mobilization time. The variable bolt pattern is shown in F
EdgeTech advises mounting the 6205s Sonar Head to the bow of a survey vessel. By placing the system at the bow, the sonar should be far enough away from most interference, such as hull echoes, propeller noise, and wake.

2.1.2 Housing

The 6205s shells are thermoformed Polycarbonate (PC). The Internal Frame is made of electropolished 316 stainless-steel and Acetal Homopolymer (Delrin). The housing supplies a streamline body for efficient underwater maneuvers rated up to 12 knots, while protecting the SVS, arrays, and deck cable connections.
NOTE: Although the 6205s can handle transit up to 12 knots, survey
speeds should be constrained to 4-5 knots or less. However, EdgeTech recommends removing the Sonar Head from the water during transit above 7-8 knots.

2.1.3 Sonar Processor

The 6205s Sonar Processor has a built-in Windows 7 Embedded PC. The main firmware installed on the embedded PC is called Sonar.exe, which controls the sonar’s hardware and performs specific functions, such as signal processing and time synchronization of the acquired data.

2.1.4 Sound Velocity Sensor

The 6205s Sonar Head has a flooded section that is used to house an AML Sound Velocity Sensor (SVS), which provides a response time of 47 μs, a resolution of 0.001 m/s, and a theoretical accuracy of ±0.025 m/s. A closer look at the SVS is presented in F
EdgeTech recommends collecting a sound velocity profile, especially in the area where you collect test data. The water being operated in likely does not have a uniform sound velocity, and depending on how drastic the profile is, a depth error as large as 1.6 m has been observed.

2.1.5 Sonar Arrays

The 6205s provides single frequency Bathymetry and Simultaneous Dual Frequency Side Scan Sonar.
The Side Scan Sonar operates at 230/550 kHz, 540/850, or 550/1600 kHz and collects simultaneously on both frequency channels. Bathymetry is obtained on either the 230 kHz or the 550 kHz. The 6205s utilizes two arrays (port and starboard) to map the seafloor much like a Dual Head Multibeam System. Each 6205s Array is constructed using 10 independent longitudinal PZT elements and two multi-segment PZT strings. The two multi-element strings (one per Side Scan Frequency) are used for the transmit function and as a full resolution side scan receiver. The remaining 10 elements make up approximately half-wavelength spaced array of sensors for its bathymetry receiver.

2.1.6 Acoustic Center

The individual Acoustic Centers of each Array (port and starboard) converge at a single point along the centerline of the 6205s Sonar Head. Therefore, when entering sonar head offsets into the Third-Party acquisition and processing software, the port and starboard array offsets (or sometimes referred to as Sonar Head 1 and Sonar Head 2, respectively) are identical in all dimensions.
The EdgeTech convention for X, Y, and Z is:
• X is positive to starboard
Y is positive forward
• Z is positive down
Remember that the individual Acoustic Centers for both port and starboard converge on the centerline (or X = 0).
NOTE: The Acoustic Center along the Y axis is different for the 230kHz
model than the 550kHz model.
