Radiative transfer of ultrasound
Radiative transfer theory is used to model the multiple scattering of diffuse ultrasonic waves in two types of random media. The first type is an isotropic, homogeneous medium containing randomly oriented, randomly located scatterers. The scatterers are assumed to be uncorrelated. This assumption …

A DNS capability for obtaining underwater light field and retrieving upper ocean conditions via in-water light measurements
… applied by means of Monte Carlo method to solve radiative transfer for both unpolarized and polarized natural light radiation, especially strongly affected with dynamic air-sea boundary conditions and inhomogeneous ocean turbulence. In the thesis, radiative transfer theory and Monte Carlo method …

A two-dimensional transfer model
The fundamental definitions of radiative transfer theory are given and the two-dimensional equation of transfer is derived, density of radiation is defined, and two-dimensional two-intensity transfer model is presented. An operational interpretation of the latter model is given interms of military …

The Polarimetric Impulse Response and Convolutional Model for the Remote Sensing of Layered Vegetation
… for random forest canopies by using the Vector Radiative Transfer (VRT) Theory with success, however, these models often rely on purely time-harmonic formulations and approximations to integrals. Forms of VRT models have recently been developed which account for a Gaussian pulse incident …

Scale closure in upper ocean optical properties : from single particles to ocean color
… were investigated. A combination of Mie theory and flow cytometry was used to determine the diameter, complex refractive index (n+n'i), and optical cross-sections of individual particles, based on a method developed in the laboratory using phytoplankton cultures. Individual particle …

Evaluation of a semi-analytical approach to the retrieval of water quality parameters from optical data in European coastal Case-II waters
… in coastal waters to investigate the validity of radiative transfer theory and bio-optical models that have been developed primarily for open ocean waters. To obtain water quality parameters from reflectance measurements we employ a non-linear inversion method (Gauss-Newton). Algorithm parameters …

On The Use Of Variable Coherence In Inverse Scattering Problems
… coherence gating. Within the framework of the radiative transfer theory, this dissertation demonstrates that the short range correlation properties of a medium under test can be recovered by varying the size of the coherence volume of an illuminating beam. Nonetheless, the radiative transfer …

Modélisation de l’émission micro-onde hivernale en forêt boréale canadienne
… en forêt boréale, le couplage d’un modèle de transfert radiatif (MTR) micro-onde passive (qui prend en compte les contributions du sol, de la neige, de la végétation et de l’atmosphère) avec un modèle de neige pour l’inversion du SWE semble une avenue prometteuse. La thèse vise donc à coupler …

Variability of aerosol and cloud optical properties and their effect on the transfer of solar irradiance in the atmosphere
… these parameters have on the solar radiation transfer in the atmosphere. The first chapter provides a brief description of the basic concepts of radiative transfer. The radiative transfer theory is described, along with various approximations, used to address specific atmospheric transfer …

Propagation and Scattering of Waves by Terrain Features
… a surface is then examined. Starting from the radiative transfer equations, a model is developed herein for scattering from vegetated rough terrain. It assumes completely incoherent scattering and includes contributions from both the vegetation and the surface scattering along with a relatively …
