A Coupled Simulation of Synthetic Aperture Radar Image of the Narrow Ship Wake
A coupled simulation is implemented to simulate the synthetic aperture radar (SAR) image of the different patterns of the ship wakes. The computational fluid dynamic (CFD) method is utilized to simulate the flow fields of the ship far wakes, which are a little different from the traditional Kelvin wake with a fixed spreading angle. The different modes of the wakes with different Froude numbers of the ships are discussed. The modulation effects of the wakes are considered based on a faceted scattering model and SAR bunching imaging model, respectively. The simulation results shows that the coupled simulation, which is more flexible and reasonable, can be widely used to explain and model the multi-physics issues about the SAR image of ship wakes.
