Abstract:

The large amplitude wave were observed in ship wakes and the large radar returns including sharp angular dependences suggest that first order Bragg scattering theory is inadequate to describe the experiments. Here we consider a simple theory to qualitatively investigate higher order effects. There are two important limitations. The large amplitude waves observed in ship wakes and the large radar returns, including sharp angular dependencies, suggest that first order Bragg scattering theory is inadequate to describe the experimental data. This report considers a simple theory which concludes that there can be look angles such that second order scattering can be larger than first order. These conclusions are very tentative because of the lack of knowledge of the Basic wave fields.
