Multibeam echo sounders for naval applications

Modern multibeam echo sounders provide not only bathymetric depth data, but much more information and advanced functionality. Therefore, these echo sounders can be used for a wide range of naval applications for naval surface ships and submarines. The Wärtsilä ELAC SeaBeam medium-depth multibeam echo sounder systems, operating in the 26 kHz band or 50 kHz band, provide high-resolution water column imaging (WCI) data and FM processing capabilities for increased measurement ranges and improved range resolution. Combined with high-sophisticated online visualisation and beam stacking of WCI data, automatic object detection capabilities and different transmission beam steering modes during stationary or survey operations, these multibeam systems are well-suited for several naval applications. Such applications are, for example, covert bottom mapping, bottoming procedures for submarines, submarine hunting in confined and shallow waters and submarine rescue operations of surface ships.
