6205s BATHYMETRIC AND SIDE SCAN SONAR 0020300_REV_E
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's 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.
EdgeTech has designed the 230 kHz/550 kHz model 6205s Sonar Head with Field Exchangeable Arrays to
mitigate frequency tradeoffs. The bathymetry frequency can be switched from the low-frequency channel
to the high-frequency channel or vice versa.
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
in F
IGURE 2-1.
