Electromagnetic Scattering From Foliage Camouflaged Complex Targets

An analysis of electromagnetic scattering from finite-width strips

Electromagnetic scattering from anorthotropic

We investigate electromagnetic wave propagation in an inhomogeneous anisotropic medium. For the case of an orthotropic medium we derive the Lippmann-Schwinger equation, which is equivalent to a system of strongly singular integral equations. Uniqueness and existence of a solution is shown and we examine the regularity of the solution by means of integral equations. We prove the innnite Fr echet...

Electromagnetic Scattering from Multiple Cylinders

During the last several decades, electromagnetic scattering from multiple cylinders has been an active research topic of in many areas, such as microwave remote sensing, theory of photonic crystals, atmospheric sciences, and so on. Rigorous theoretical treatment is therefore of critical importance. A large body of available studies in the literature concerns with two dimensional scattering, suc...

Electromagnetic Scattering From Chiral Media

Time and frequency domain analysis of electromagnetic plane wave scattering from chiral media are presented. The frequency domain solution deals with two-dimensional scatterers using a boundary value and an iterative techniques for the scattering from a number of parallel circular cylinders forming a scatterer of arbitrary cross-section. The time domain solution is based on a scattered field fi...

Into the woods: visual surveillance of non-cooperative and camouflaged targets in complex outdoor settings

Autonomous video surveillance and monitoring of human subjects in video has a rich history. Many deployed systems are able to reliably track human motion in indoor and controlled outdoor environments, e.g. parking lots and university campuses. A challenging domain of vital military importance is the surveillance of non-cooperative and camouflaged targets within cluttered outdoor settings. These...
