Improved Compact Polarimetric SAR Quad-Pol Reconstruction Algorithm for Oil Spill Detection
TLDR
An improved reconstruction algorithm is proposed for compact polarimetric (CP) synthetic aperture radar (SAR) on oil spill detection that can iteratively reconstruct quad-pol SAR images from CP SAR data.Abstract:
An improved reconstruction algorithm is proposed for compact polarimetric (CP) synthetic aperture radar (SAR) on oil spill detection. Based on the differences in statistical behavior between open and oil-covered sea surfaces, the proposed algorithm can iteratively reconstruct quad-pol SAR images from CP SAR data. During the experiment, it outperformed two existing compact SAR reconstruction algorithms in terms of both statistical and information theoretical analysis.read more

Application of Deep Networks to Oil Spill Detection Using Polarimetric Synthetic Aperture Radar Images
TL;DR: Deep learning algorithms such as the stacked autoencoder (SAE) and deep belief network (DBN) are applied to optimize the polarimetric feature sets and reduce the feature dimension through layer-wise unsupervised pre-training to show that oil spill classification achieved by deep networks outperformed both support vector machine (SVM) and traditional artificial neural networks with similar parameter settings.

Model-Based Pseudo-Quad-Pol Reconstruction from Compact Polarimetry and Its Application to Oil-Spill Observation
TL;DR: This study proposes a new method for pseudo-quad-polarization reconstruction from compact polarimetry based on the three-component decomposition by using the decomposed powers, and shows that the proposed model-based method is of great potential for oil-spill observation.

Compact polarimetry based on symmetry properties of geophysical media: the /spl pi//4 mode
TL;DR: The polarization uniqueness in transmission of this mixed basis mode, hereafter referred to as the /spl pi//4 mode, maintains the standard lower pulse repetition frequency operation and hence maximizes the coverage of the sensor.

Polarimetric Analysis of Backscatter From the Deepwater Horizon Oil Spill Using L-Band Synthetic Aperture Radar
TL;DR: The results show that synthetic aperture radar can be used to measure the oil volumetric concentration in a thick slick, and the most reliable indicator is the major eigenvalue of the coherency matrix, which is approximately equal to the total backscatter power for both oil in the slick and clean sea water.
