A New Method to Extract the Polarimetric Parameters in Imaging Radars

Abstract

Abstract-In this paper, a statistical approach to evaluate randomly rough surfaces (RRS) in an inverse scattering problem is presented. Whereas in these investigations the roughness criterions possess random variables, the use of deterministic techniques such as the target decomposition (TD) can not be useful by itself as a tool of analysis. In these conditions, a statistical approach is essentially required to evaluate the target parameters. The goal of this study is the estimation of the polarimetric signatures, such as the scattering mechanism α and the entropy H, via a novel approach including the combination of TD and a new statistical model. To validate our work, SAR data sets, provided by the European Space Agency (ESA), are analyzed and compared with the simulation results.

A Statistical Approach to Monitor Earth's Surface in Remote Sensing Applications

“…It should be pointed out that among these parameters, the˛-angle is a field of growing interest. This signature is strongly influenced by target parameters, having statistical features, such as soil contents and geometrical shapes, in the surface scattering (Zakeri et al, 2008;Storvold et al, 2006;Chen et al, 2006;Bourlier & Berginc, 2002). Among these, the dielectric constant, depending on the moisture of the soil, extremely affects backscattered waves and polarimetric signatures.…”

High-power first-order Gaussian pulse-fed bow-tie time-domain antenna

“…Because of the increasing request of the target identification, imaging [3], anti-stealth and anti-jamming and direction on the transmission of information content, the forefront of radar pulse modulation and pulse width have reached the order of ns or ps. Timedomain electromagnetism gets a good application in the impulse radar [4].…”
