The precise acquisition of water depth data in nearshore shallow waters bears considerable strategic significance for marine environmental monitoring, resource stewardship, navigational infrastructure development, and military security. Conventional bathymetric survey methodologies are constrained by their spatial temporal limitations, thus failing to satisfy the requirements large-scale, real-time surveillance. While satellite remote sensing technologies present a novel approach inversion waters, attaining high-precision areas characterized elevated levels suspended sediments diminished transparency remains formidable challenge.
