Depth Determination Accuracy of the Modified Prony Method in a Swath Mapping Application

Grall, Piotr / Marszal, Jacek

This article presents the performance of the modified Prony method in a swath mapping application. Depth determination accuracy is assessed by processing raw signal acquired by an EdgeTech 6205 swath bathymetry system over flat seafloor. An updated version of the method, proposed previously by the authors, is used to determine the number of signal echoes. The number of signal echoes is essential for performing the low-rank approximation of the data matrix in the modified Prony method. The achieved accuracy results are also compared to the results of other methods applied to the same signal and International Hydrographic Organization standards.
