The HydroSweep MD/50 is a high resolution multibeam echosounder ideally suited for seabed mapping in mid and shallow water based on a sonar frequency range between 52 kHz to 62 kHz. Beside bathymetric depth information from 5 m to more than 2000 m, sidescan data and backscatter data for seabed classification can be acquired.
The beam width for HydroSweep MD/50 can be arranged as combination of 0.5° or 1° along track and 0.75° or 1.5° across track.
Effects of severe ship motion to survey data are compensated by active beam steering as well as additional multi-ping ensonification. The HydroSweep MD/50 applies 4x multipings, which means that four swaths are transmitted simultaneously per ping slightly tilted along track. This results in gapless surveying at higher ship’s speed.
Acoustic footprints can be arranged in either „equal-angle“ or „equal-distant“ pattern.
A High Order Beamforming bottom detection algorithm is used to achieve up to 960 soundings per single ping with the best possible accuracy in order to meet IHO SP44 accuracy standards.
