DT1H Getting Dash Lines When In Use
You may be experiencing the diffusion of the sonar signal in many directions resulting in
signal weakening through Refraction or Backscatter, primarily due to the material properties
of the areas.
Backscatter: The deflection of acoustic signals in a scattering process through an angle
greater than 90 degrees. Backscatter is the term commonly used to describe the return of
energy from the seabed to the receiver in an active sonar.
Refraction: The change of direction of a sound beam when passing obliquely from one
medium into another, where its wave velocity is different.
Refraction is a type of ray bending that will affect acoustic returns for proper sonar imaging.
This occurs when sonar pulses encounter thermal zones, silt, salinity changes. Under these
conditions the beam can be refracted sharply to the seafloor severely limiting range. If you
are experiencing one of these conditions, first verify that the sonar is working by placing
your ear up to the sensor and listening for the tick. If you hear the ticking sound, you may
have to discontinue use under these conditions.
