A Noise De-Correlation Based Sun Glint Correction Method and Its Effect on Shallow Bathymetry Inversion

open access: yesRemote Sensing, 2022
Sun glint on the sea surface is the unavoidable noise in optical remote sensing images. Water depth retrieval based on optical remote sensing images is vulnerable to sun glint contamination.

Multiple sites HFSWR ocean shallow water depth and current inversion

open access: yesActa Physica Sinica, 2014
In order to extract the ocean dynamic parameters from shallow water, water depth, and current inversion at multiple (three or more) sites, HFSWR (high frequency surface wave radar) sea echo is developed. In this paper the inversion principle and theoretical model are presented in detail, and the proposed idea is verified for three or more than three ...
