A new model for rough surface scattering is presented; the model has a form similar to the small slope approximation (SSA) of Voronovich, but with modified kernel functions. As with the SSA, when including two field series terms in the solution the m

The second-order local curvature approximation (LCA2) is a theory of rough surface scattering that reproduces fundamental low and high frequency limits in a tilted frame of reference. Although the existing LCA2 model provides agreement with the first

The influence of waves on the mean flow is derived on a rotating earth in the form of interaction stresses and a mass flux in the averaged momentum balance and mass conservation equations, respectively, using Hasselmann's formalism and keeping only t

This paper is the third in a series discussing a new approximate bistatic model for electromagnetic scattering from perfectly conducting rough surfaces. Our previous approach supplemented the Kirchhoff model through the addition of new terms involvin

We present a new stochastic theory for delay-Doppler mapping of the ocean surface for bistatic scattering. This stochastic theory should complement nicely the previous theories for the Global Positioning System (GPS) reflected signals from ocean surf

Under the two–scale hydrodynamic model for ocean surface waves, short waves are modulated hydrodynamically by long waves. An exact numerical simulation of the two–scale hydrodynamic process shows that the most commonly used modulation transfer fu

The modulation of short ocean waves by longer ones is a likely contributor to the radar altimeter's electromagnetic ranging bias (EM bias). An analytic model to account for this component of the EM bias is developed here under a two-scale two-dimensi

This paper is a companion to our previous contribution deriving a new approximate bistatic model for electromagnetic scattering from perfectly conducting rough surfaces. We evaluate this model numerically and compare it with an ‘exact’ numerical

Two fundamentally different theories on nonlinear surface waves are scrutinized. The first is a Stokes-like perturbation about a mean equilibrium level. The second is a perturbation about the surface itself by truncation of the Hamiltonian which rela

In this paper, we extend the Kirchhoff approach, which is widely used for near-nadir backscattering calculations, to include the proper polarization sensitivity for general bistatic scattering from gently sloping, perfectly conducting surfaces. Previ
