“…There have been many experimental studies of radar backscatter from the sea sur face at near-grazing angles. Both the backscatter cross-section and higher order statistics have been reported (Atanassov et al 1990;Chan 1990;Helmken 1990). Some progress has been made in modelling the higher-order statistics (Jakeman & Tough 1988), but there are few studies in which the backscatter cross-section obtained in experiments has been compared with theory (Bass et al 1968a, b).…”

We present the numerical study of scattering of scalar waves from impenetrable two-dimensional periodic surfaces of arbitrary shape. Nearly all numerical simulations of scattering of waves from rough surfaces in the past have been limited to one-dimensional surfaces and moderate angles of incidence. By making the surface infinite and bi-periodic, it becomes possible to simulate numerically scattering from two-dimensional surfaces, even down to grazing angle. Only impenetrable surfaces are considered. Some calculations are presented, and are used to compare with the small perturbation, or Rayleigh–Rice theory. It is found that for near grazing incidence, Neumann boundary condition, the small perturbation theory gives inaccurate values, especially near the backscatter direction.
