HydroSweep MD/50
The Hydrosweep MD/50 Is a High Resolution Multibeam Echosounder Ideally Suited for Seabed Mapping in Mid and Shallow Water
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.
Description
Effects of severe ship motion to survey data are compensated by active beam steering and additional multi-ping ensonification. The HydroSweep MD/50 applies 4x multi ping, which means that four swaths are transmitted simultaneously per ping slightly tilted along the track. This results in gapless surveying at a higher ship’s speed.
Acoustic footprints can be arranged in either an „equal-angle“ or „equal-distant“ pattern. A High Order Beamforming bottom detection algorithm achieves up to 960 soundings per single ping with the best possible accuracy to meet IHO SP44 accuracy standards.
