3D Scour Monitoring Sonar Specification

The resolution of the 3D Scour Monitoring Sonar sets a new performance benchmark for short range bathymetry sonar systems. The high frequency acoustic transducer scans a narrow “pencil” beam along a swath whilst an advanced multi-return processing algorithm extracts the range to the return signals from the raw data.

In logging form the system then uses the data from the Conductivity, Temperature and Pressure transducers ( if fitted ) to calculate an accurate value for the Velocity of Sound in the water at the sonar head. The Pitch and Roll sensors provide attitude correction so that the 3D surface data is orientated correctly allowing features such as scour to be accurately quantified.
