Method for determining seafloor roughness using multibeam echosounder |
摘要 |
The present invention provides a method for determining sea floor roughness using multibeam echosounder, said method comprising providing backscatter, bathymetry and multibeam operational parameters; removing system gain from the backscatter data to obtain real seafloor backscatter data; calculating across track seafloor slope; incorporating correction factor in actual beam arrival angles; calculating seafloor area; measuring backscatter strength; obtaining backscatter strength data at 1° angle; obtaining power law parameters; using the above-obtained parameters in a seafloor roughness power law model; splicing the multibeam backscatter data; including sediment volume roughness model; and verifying the validity of the composite roughness model.
