On May 26th, invited by the State Key Laboratory of Geodesy and Earth’s Dynamics, Professor XU Qing from Ocean University of China visited the Innovation Academy for Precision Measurement Science and Technology (APM) for exchange and presented an academic report titled "SAR Remote Sensing Detection of Shallow Sea Topography in High-Turbidity Sea Areas" . The meeting was hosted by Researcher JIANG Liming from APM, Associate Researcher HUANG Ronggang and other faculty members and students participated in this academic exchange meeting.
The report mainly focuses on two aspects: the SAR image characteristics and imaging mechanisms of shallow seabed topography, as well as SAR remote sensing detection for shallow seabed topography. Firstly, it systematically introduces the SAR image characteristics of two types of underwater topographies, namely tidal channels and sand ridges, and analyzes their imaging mechanisms in detail. Then, for high-turbidity sea areas such as the Subei Shoal and the offshore areas of the Yangtze River Estuary, the latest progress in deep learning inversion of SAR images for shallow seabed topography is presented. Finally, the report provides a prospective outlook on the need for strong physical constraints in SAR inversion for shallow seabed water depth.
After the report, participants engaged in discussions on topics such as SAR imaging mechanisms, deep learning, and shallow seabed topography inversion, achieving excellent communication results.
