Classification of polarimetric radar images based on SVM and BGSA
Classification of land cover is one of the most important applications of radar polarimetry images. The purpose of image classification is to classify image pixels into different classes based on vector properties of the extractor. Radar imaging systems provide useful information about ground cover by using a wide range of electromagnetic waves to image the Earthchr('39')s surface. The purpose ...
متن کاملElectromagnetic Model Reliably Predicts Radar Scattering Characteristics of Airborne Organisms
The radar scattering characteristics of aerial animals are typically obtained from controlled laboratory measurements of a freshly harvested specimen. These measurements are tedious to perform, difficult to replicate, and typically yield only a small subset of the full azimuthal, elevational, and polarimetric radio scattering data. As an alternative, biological applications of radar often assum...
متن کاملModeling Polarimetric Sar Response of Urban Dihedrons
Microwave polarimetric models for rough dielectric dihedral corner reflectors provide helpful tools to understand the complex interaction of radar with urban land cover. After a theoretical background, we present results from a numerical analysis which takes into account the dielectric properties and roughness of the reflecting surfaces and evaluates the contributions of both coherent and diffu...
متن کاملModeling and Measurements of Scattering from Road Surfaces at Millimeter-Wave Frequencies
Millimeter-wave radar-based sensors are being considered for a number of automotive applications including obstacle detection and collision warning, true-speed, and road-surface recognition. In this paper, the interaction of electromagnetic waves with asphalt road surfaces, possibly covered with ice or water, at millimeter-wave frequencies is studied. First, an experimental procedure for determ...
متن کاملThe Extended Sub-look Analysis In Polarimetric SAR Data For Ship Detection
The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...
