Doppler Properties of Sea Backscatter Simulated with Creamer or Choppy Wave Surface Models

The accuracy of sea scattering simulations depends on both the robustness of the chosen electromagnetic model and the adequate description of the ocean surface itself. The latter consideration is particularly relevant for Doppler simulations that are sensitive to hydrodynamic (non-linear) effects in surface propagation. There are two commonly used approaches to introduce such non-linearities – the...Show More
