Sound propagation and scattering in discrete random scatterers

Polarized pulse waves in random discrete scatterers.

In recent years there has been increasing interest in the use of polarization for imaging objects in a cluttered environment. Examples are optical imaging through clouds, optical detection of objects in a biological medium, and microwave detection of objects in clutter. We extend previous studies of continuous-wave scattering to pulse-polarization scattering in discrete scatterers. We solve the...

Discrete Simulation of Sound Wave Propagation

Fast Method for High-frequency Acoustic Scattering from Random Scatterers

This paper is concerned with the uncertainty quantification of high-frequency acoustic scattering from objects with random shape in two-dimensional space. Several new methods are introduced to efficiently estimate the mean and variance of the random radar cross section in all directions. In the physical domain, the scattering problem is solved using the boundary integral formulation and Nyström...

SOUND PROPAGATION IN RANDOM MEDIA. Backscattering correction to the multiple forward scattering theory

The Parabolic Equation Method ( P E M ) is the commonly used method to deal with wave propagation in random media. This method basically requires the small ratio of wave length to correlation length (small angle scattering). Recently, de Wolf/2/ and Rino/3/ extended the PEM by including the backscattered wave, retaining the small angle scattering. In his dissertation, GroBe/4/ generalized the P...
