Abstract

By simulating the electromagnetic field over the sea-surface with a high level of precision, the characteristics of sea clutter echo could be effectively analyzed, which could lead to better maritime remote sensing systems. To fulfill this goal, the electromagnetic simulation method of dynamic sea-surface is studied: Firstly, the ocean wave spectrum model is used to reconstruct the 3D coarse sea-surface; then the metrics of electromagnetic parameters are loaded to initiate the Maxwell equations; after that, the equations are differenced to facilitate FDTD method; then the electromagnetic field distribution is achieved by solving the equations, which gives the physically precise parameters of the sea clutter and targets. The simulation experiments showed the effectiveness of this method.
