Reducing the residual error of multibeam sounding data through empirical mode decomposition based on cubic Bessel interpolation

Journal of Algorithms & Computational Technology, 2021
The systematic residual errors present in multibeam echo-sounding data cause the areas of overlap between adjacent swaths to become distorted. A method is proposed in this paper to reduce the residual error of multibeam sounding data through empirical ...
