SYSTEM DESCRIPTION
Introduction
The Simrad SH80 sonar is an omnidirectional high frequency
sonar, designed for all sized fishing vessels, both purse seiners
and trawlers. The standard frequency is 116 kHz (multiple
frequencies as option), and the beam can be electronically tilted
from +10 to –60 degrees.
Great emphasis has been placed on giving the best possible
presentations on a high resolution colour display. The processor
unit is controlled by Microsoft’s Windows XP operating
system, which result in a flexible choice of display modes for a
large range of user applications.
The signal processing and beamforming is performed in a fast
digital signal processing system using the full dynamic range of
the signals. In addition to the traditional single frequency
transceiver system, the SH80 sonar contains an advanced
frequency modulated filter system (FM).
The cylindrical multi-element transducer allows the
omni-directional sonar beam to be tilted electronically down to
-60 degrees. This allows you to automatically track schools of
fish, and to observe the whole water volume around the vessel.
A stabilization system is included for electronic pitch and roll
compensation.
