Common features for all multibeam systems Listed below are common features which are incorporated in all our multibeam systems*. Many of these features are essential to be able to ensure a dense coverage of the seafloor to fulfill requirements set by IHO S-44" and LINZ2' even in foul weather Sector transmission and stabilization Our multibeam systems apply sound velocity correction in real time. The basic algorithm performs a ray tracing process through the water column for each beam using an intersection of cones' technique that is unique to the Kongsberg multibeam systems. It also...

High density signal processing: Standard mode - 256 soundings High density signal processing: High density mode - 400 soundings Images: ©J.E Hughes Clarke, OMC/UNB High density signal processing and beam focusing The horizontal resolution is much improved compared to previous models, due to the introduction of focused beams for both transmission and reception and the new high k density signal processing technique. Near-field focusing is essential for retaining angular resolution. On reception this is done dynamically (focal point is shifted as function of time/range) and on transmit each...

Extended coverage by use of chirp technology The use of new frequency independent hardware makes it possible to generate other signals than continuous wave (CW) pulses, like frequency modulated chirp (FM) waveforms for extended range performance and with pulse compression on reception. The use of FM gains approximately 15dB in signal-to-noise-ratio compared to CW. Seabed imagery and water column data In addition to the sounding data all systems produce high resolution backscatter data and water column data. Both can be logged simultaneously with bathymétrie data. Multibeam Backscatter Data...

CeoSwath Plus data Glomma River in Norway. Data courtesy ofNCU Wide swath bathymetry system Kongsberg Maritime acquired CeoAcoustics in 2008. The company was already then well established and produced proven sidescan systems, sub-bottom profilers and wide swath bathymetry systems. What is a wide swath system? A wide swath bathymetry system is also called by several other names, "phase measuring bathymétrie sonar system", "interferometric multibeam" or "bathymétrie side- scan system". Swath bathymetry systems use two different technologies to obtain the bathymetry across the swath. A...

Phase measuring systems are very productive in the shallow water environment, where they cover a wide area with a single swath and simultaneously acquire true geo-referenced side scan data. CeoSwath Plus data 3D view - Simultaneous acquisition of wide swath bathymetry and geo-referenced side scan data.

SYSTEMS FOR ALL SURVEY APPLICATIONS For shallow water surveys, inspection, ROV and Good knowledge of shallow water bathymetry is vital to a wide range of marine activities. Surveys for navigation channels, ports and harbors, lake and dam management, environmental mapping, marine archaeology, marine construction, cable landfalls and hydrodynamic modeling all rely on accurate and detailed information on the water depth. Such surveys are mainly in waters less than 50m deep, with many in the zone from 20m water depth to the shoreline. High resolution, complete coverage, high accuracy, and...

EM 3002 – From shallow to high resolution surveys The EM 3002 is a well proven multibeam for shallow water and for high resolution surveys. The operating range is from 0.5m to more than 250m, with a maximum coverage of 200m (dual system). Due to its small sonar heads it is ideal for permanent or portable deployment on launches or any vessels of opportunity either in hull or over the bow, but also for installation on ROV and AUV. The system can be delivered either with one sonar head or with two for increased coverage to more than 200m or almost to the water surface. Two different sonar...

GeoSwath Plus - For shallow surveys with wide swath requirements CeoAcoustics GeoSwath Plus is the market leader in the phase measuring bathymétrie sonar technology and is a well proven system. The system simultaneously acquires swath bathymetry and true side scan data with a swath coverage of up to 12 times the water depth. This makes the GeoSwath Plus a very productive survey tool for the shallow water environment producing bathymetry data shown to match I HO S-44 special order accuracy. Three different frequency versions are available, 125, 250 and 500kHz with depth performances of 200,...
