A Depth-Adaptive Waveform Decomposition Method for Airborne LiDAR Bathymetry [PDF]

open access: yesSensors, 2019
Airborne LiDAR bathymetry (ALB) has shown great potential in shallow water and coastal mapping. However, due to the variability of the waveforms, it is hard to detect the signals from the received waveforms with a single algorithm.

Waveform inversion based on wavefield decomposition [PDF]

open access: yesGeophysics, 2016
ABSTRACT Full-waveform inversion (FWI) is a technique for determining the optimal model parameters by minimizing the seismic data misfit between observed and modeled data. The objective function may be highly nonlinear if the model is complex and low-frequency data are missing.
