processing have been supported by the Danish National Research Foundation. Abstract A new edge detector for polarimetric SAR data has been developed. The edge detector is based on a newly developed test statistic for equality of two complex covariance matrices following the complex Wishart distribution and an associated asymptotic probability for the test statistic. The new polarimetric edge de...

This report describes algorithms which make use of polarimetric radar information in the detection and discrimination of targets in a ground clutter background. The optimal polarimetric detector (OPD) is derived; this algorithm processes the complete polarization scattering matrix (PSM) and provides the best possible detection performance from polarimetric radar data. Also derived is the best l...

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...

Present fully polarimetric synthetic aperture radar (SAR) systems often update calibration techniques to further enhance the accuracy to the polarimetric data. In this paper, we propose a modified method to estimate the value of crosstalk based on the corrected observed value. Since Ainsworth calibration algorithm firstly set the value of k to be one. And the value of k relates to the copolariz...

We have used infrared polarimetric imaging with NICMOS to determine precisely the position of the star that illuminates (and presumably generated) the bipolar, pre-planetary reflection nebula RAFGL 2688 (the Egg Nebula). The polarimetric data pinpoint the illuminating star, which is not detected directly at wavelengths ≤ 2 μm, at a position well within the dark lane that bisects the nebula, 0. ...

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....

The intent of this paper is to explore the application of information obtained from fully polarimetric data for land cover classification. Various land cover classification techniques are available in the literature, but still uncertainty exists in labeling various clusters to their own classes without using any a priori information. Therefore, the present work is focused on analyzing useful in...

There is currently widespread interest in the development of radar sensors for the detection of surface and buried targets and the remote sensing of land, sea and ice surfaces. An important feature of electromagnetic radiation is its state of polarisation and a wide range of classification algorithms and inversion techniques have recently been developed based on the transformation of polarisati...
