Low frequency seabed scattering at low grazing angles.
Low-frequency (LF) seabed scattering at low grazing angles (LGA) is almost impossible to directly measure in shallow water (SW), except through inversion from reverberation. The energy flux method for SW reverberation is briefly introduced in this paper. The closed-form expressions of reverberation in an isovelocity waveguide, derived from this method, indicate that in the three-halves law rang...
متن کاملCharge transfer at large scattering angles in the strong-potential Born approximation
We have calculated the Is-Is charge transfer probability for large projectile scattering angles in asymmetric ion-atom collisions, using the strong-potential Born approximation and including the effect of recoil on the projectile states non-perturbatively. A significant angular dependence is found. Numerical results for Is-Is capture in 0.320 MeV proton impact on C and Ne are presented, showing...
متن کاملMolecular scattering and Born-Oppenheimer approximation
In this paper, we study the scattering wave operators for a diatomic molecules by using the Born-Oppenheimer approximation. Assuming that the ratio h between the electronic and nuclear masses is small, we construct adiabatic wave operators that, under some non trapping conditions, approximate the two-cluster wave operators up to any powers of the parameter h.
متن کاملNumerical Investigation of Radar Scattering from the Sea Surface at Small Grazing Angles
The scattering from measured and modeled sample one-dimensionally rough water surfaces is being calculated using two distinct extensions of the standard moment method (MM) that allow application at arbitrarily small scattering angles. The first method is a hybrid approach that extends the moment method using the geometrical theory of diffraction (GTD). The front and back faces of the surface ar...
متن کاملGeoacoustic Modeling: High-Frequency Scattering from Heterogeneous Rough Sea Beds at Shallow Grazing Angles (extension)
There are different mechanisms of seabed scattering which are due to different types of seabed medium irregularities, which are roughness of the seabed interfaces, and volume heterogeneity: continuous (spatial fluctuations of the sediment acoustic parameters) and discrete scatterers (or sediment inclusions, such as relatively large shells and shell fragments). Given different environmental cond...
