A new approach for fast and high-resolution interferometric bathymetry

This paper deals with a new bathymetry processing for multibeam echosounders based upon interferometry. Several issues are discussed concerning the number of beams to be formed, the optimal interferometer configuration in terms of minimal angular error, and the multitarget detection. The algorithm i...

Zusammenfassung:This paper deals with a new bathymetry processing for multibeam echosounders based upon interferometry. Several issues are discussed concerning the number of beams to be formed, the optimal interferometer configuration in terms of minimal angular error, and the multitarget detection. The algorithm is illustrated by data from a 300-kHz multibeam echosounder recorded over a wreck area.
