Simulation of Multi-Layer Rough Surfaces Media in the Passive Millimeter-Wave Imaging

An electromagnetic model for detecting explosives under obscuring layers

Recently, there has been increasing interest in object imaging and detection behind obscuring layers because of applications in detection of improvised explosive devices (IEDs) and suspicious materials. Millimeter (MMW) and terahertz waves show promise in detecting and imaging objects through clothing or packaging materials. In this paper, we discuss an electromagnetic model based on a multi-la...

Experimental Studies of Millimeter- Wave Scattering in Discrete Random Media and from Rough Surfaces

Imaging and Coherence in Rough Surface and Object Scattering

This paper is concerned with two problems. First, when the object is near a rough surface such as an ocean or terrain, and the transmitter and the receiver are also located near the surface, how can we image or detect the object which may be obscured by multiple scattering due to rough surface scattering. Second, even though multiple scattering generally increases the incoherent field, there ar...

Numerical Analysis of Electromagnetic Scattering from a Dielectric Rough Surface Cylinder

1.Introduction The wave scattering from rough surfaces is an important problem which closely relates to the measurement technology or diagnosing techniques by using microwave, millimeter wave, light wave or acoustic wave (1). Various kinds of theoretical models and methods for analyzing the wave scattering from random rough surfaces have been proposed so far. However, they have often used appro...

A Partial Coherent Physical Model of Third and Fourth Stokes Parameters of Sastrugi Snow Surfaces over Layered Media with Rough Surface Boundary Conditions of Con- Ical Scattering Combined with Vector Ra- Diative Transfer Theory

In this paper, a partial coherent approach is used to study the third and fourth Stokes parameters in passive microwave remote sensing of Sastrugi snow surface over layered snow structures. The incoherent part of the model consists of using radiative transfer theory for the snow layers. The coherent part of the model is using numerical solutions of Maxwell equations to derive the bistatic scatt...
