Abstract

It is challenging to estimate ocean surface currents from along-track interferometric (ATI) data due to the complexity of the ocean environment. In order to complete the process from modeling the ocean surface signals to extracting the ocean surface currents, this research integrates dynamic sea surface modeling imagery with an iterative technique to inverse the currents. To complete the simulation analysis of time-varying ocean surface imaging, ocean surface backscatter coefficients and ocean surface echoes are constructed using the wave spectrum model as the basis. The ATI data from the simulation modeling are inverted using the iterative inversion algorithm of the Synthetic Aperture Radar (SAR) ocean surface currents field, and the accuracy of the inverse ocean surface currents field obtained reaches 0.1 m/s, proving the viability of the whole system.
