An analysis of polarimetric synthetic aperture radar (SAR) space observations usage for measuring Faraday rotation angle plane-polarized electromagnetic radiation on the satellite-Earth-satellite route and calibrating is performed. It shown that technical characteristics SAR, movement during survey features waves reflection from rough Earth's surface, as well small-scale ionospheric inhomogenei...

Detection characteristics, resolution capability, and target coordinates measurement accuracy of Multisite Radar Systems (MSRSs) consisting of Ultra-Wideband (UWB) radars are analyzed. Two types of UWB radars are considered: using short carrier-free pulses and using pulses with carrier frequencies. Target radial dimensions are assumed to be much greater than range resolution cells of UWB radars...

A fully polarimetric borehole radar system with four combinations of dipole and cylindrical slot antennas, as shown in Fig. 1, was developed to acquire fully polarimetric data sets in drilled boreholes [1]. The system in conjunction with a methodology of radar polarimetry analysis, proposed in previous (a) Measurement configuration (b) Antenna arrangements for polarimetric data collection Fig. ...

In this paper, we present a comparison between several algorithms for oil spill classifications using fully and compact polarimetric SAR images. Oil spill is considered as one of the most significant sources of marine pollution. As a major difficulty of SAR-based oil spill detection algorithms is the classification between mineral and biogenic oil, we focus on quantitatively analyzing and compa...

distribution of magnetic fields in the quiet-sun internetwork areas has been affected by weak polarization (in particular stokes q and u) signals. to improve the signal-to-noise ratio (snr) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. in this study, we aim to investigate a proper temporal-integration time with which...

1. Introduction This paper discusses the polarimetric correlation coefficient to extract useful feature from polarimetric Synthetic Aperture Radar (SAR) data. Several methods have been proposed to extract polarimetric feature, such as Polarimetric Entropy-Alpha, three-component scattering model, Huynen parameters and so on

A study on sea oil spills observation by means of polarimetric Synthetic Aperture Radar (SAR) data is accomplished. The polarimetric approach presented in this paper is based on the combined use of a polarimetric Constant False Alarm Rate (CFAR) filter to detect dark patches over SAR images and the Target Decomposition (TD) theorem to provide extra polarimetric features to the decision process....

ABSTRACT: In this paper we propose the polarimetric response in target characterization and SAR radar image classification. Polarimetric response is a graphical representation that is dependent on transmitted and received polarizations. The polarimetric response is given in a pair of two curves, one represents the copolarized response and the second represents the cross-polarized response. The ...

This paper introduces an approach to the classification and interpretation of SAR data using complementary polarimetric and interferometric information. Strictly polarimetric and polarimetric interferometric data are first analyzed and classified separately. An unsupervised polarimetric segmentation, based on multivariate Wishart statistics, is applied to one of the separate polarimetric datase...

Abstract This article summarizes research and risk reduction that will inform acquisition decisions regarding NOAA’s future national operational weather radar network. A key alternative being evaluated is polarimetric phased-array (PAR). Research indicates PAR can plausibly achieve fast, adaptive volumetric scanning, with associated benefits for severe-weather warning performance. We assess the...
