Assessment of compact polarimetry over different tropical environment and dataset
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010This paper presents different radar polarimetric modes over different study sites in Tropical environment: Full polarimetry (FP), Dual Polarimetry (DP) and Compact Polarimetry (CP). By using SVM classification, we show the capabilities of each polarimetric mode linked to the scattering model assumption of the fully polarimetric reconstruction for CP ...

Target Detection on the Ocean With the Relative Phase of Compact Polarimetry SAR
IEEE Transactions on Geoscience and Remote Sensing, 2013This paper discusses the potential for automatic ocean surveillance using compact linear polarization (CL-pol) synthetic aperture radar (SAR), with large area coverage. Here, the target is a wind farm in the North Sea. The relative phase, as derived from CL-pol SAR, is employed for detection of the wind turbines, apart from the wind turbines' wakes ...

New parameters in compact polarimetry for ocean target detection
IET International Radar Conference 2013, 2013In this paper, we develop three new parameters for compact polarimetry to a particular application in synthetic aperture radar (SAR) maritime surveillance, i.e., the joint oil-spill and ship detection. Based on the X-Bragg rough surface scattering model, we investigate the capability of compact polarimetry, a dual-polarized system, for sea surface ...

Potential assessment of SAR in compact and full polarimetry mode for snow detection
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011This paper presents the comparison between the potential of SAR data in compact polarimetry (CP) and full polarimetry mode for snow detection. Eigenvalues based analysis and developed procedure have been used for this inter-comparison. It has been found over the part of rugged Siachen glaciated terrain, Indian Himalaya that dual polarization and ...

Precision and widefield polarimetry with the Australia Telescope Compact Array
AIP Conference Proceedings, 2002This paper describes some of the polarimetry done with the Australia Telescope Compact Array (ATCA). Comparatively low and stable instrumental polarization allows high quality polarimetric images to be formed. The instrument has proven particularly successful in studying low level circular polarization.

Compact antenna element for high‐resolution SAR polarimetry applications
Electronics Letters, 2013 For high‐resolution synthetic aperture radar polarimetry applications, a compact broadband dual‐polarised antenna element with high port isolation and low cross‐polarisation is investigated. The size of the element is 19 × 19 × 40 mm, which is much smaller than the traditional dual‐polarised horn.

Compact static Fourier transform imaging spectropolarimeter based on channeled polarimetry
Optics Letters, 2010The theoretical operation and experimental demonstration of a Fourier transform imaging spectropolarimeter for real time measurement of the polarization state of light are presented. The spectropolarimeter uses a Wollaston prism as a birefringent interferometer and two high-order retarders to incorporate channeled polarimetry.

A Tool for Analysis and Calibration of Compact Polarimetry SAR Mode Anomaly
IEEE Geoscience and Remote Sensing Letters, 2018Transmit wave polarization (i.e., ellipticity and roll) deviation from the ideal or intended transmit mode affects compact polarimetry (CP) products and associated data exploitation. Hence, it is important to evaluate such effects on the CP model and account for the associated variations through data exploitations.

Detection of wind farm using the relative phase of compact polarimetry SAR
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012This paper discusses the potential for automatic ocean surveillance using compact linear polarization (CL-pol) SAR, with large area coverage, including high sea state conditions. Here, the target is a wind farm in the North Sea. The relative phase derived from CL-pol SAR is employed for detection of the wind turbines, apart from the wind turbines ...
