Qualified Soundings From Interferometric Bathymetry

[...]critical information is delivered for safe and efficient navigation routing, scour inspection around bridges, piers and other structures, as well as accurate accounting for volumes of dredge material, quantification of water resources and rapid environmental assessment of critical shallow-water habitats. While the quick solution involved more robust filtering (e.g., amplitude, unit circle, bottom tracking), more dynamic TVG options or greater variety of averaging methods, L-3 Klein pursued further development to reduce the causes of high noise levels; produce cleaner match-filtered, chirp-pulse signal levels; improve characterization of the sources of acoustic attenuation, variability in noise for measuring SNR and bathymétrie measurement uncertainty; and determine solutions for removing low-quality soundings from multipath or masking in shadows.\n The HC3500 can be deployed by one person.
