CP-IRGS: A Region-Based Segmentation of Multilook Complex Compact Polarimetric SAR Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The Canadian RADARSAT constellation mission (RCM) is represented by three synthetic aperture radar (SAR) satellites, each of which includes a compact polarimetry (CP) mode. CP is advantageous because it provides increased backscatter information relative

Investigation of C-Band SAR Polarimetry for Mapping a High-Tidal Coastal Environment in Northern Canada

Remote Sensing, 2020
Synthetic Aperture Radar (SAR) has been used in characterizing intertidal zones along northern Canadian coastlines. RADARSAT-2, with its full polarimetric information, has been considered for monitoring these vulnerable ecosystems and helping enhance the

Retrieval and Attribution of Tropical Cyclone Vertical Tilt From SAR and Infrared Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Tropical cyclones (TCs) are destructive natural hazards, and their vertical tilt, defined as the displacement between the sea surface center and cloud top center, plays a key role in storm structure and intensity changes. This study constructed a global satellite‐based tilt data set from 1,024 paired synthetic aperture radar (SAR) and infrared

Ocean Wave Information Retrieval Using Simulated Compact Polarized SAR from Radarsat‐2

Journal of Sensors, Volume 2018, Issue 1, 2018., 2018
The main objective of this paper is to demonstrate the capability of compact polarized (CP) synthetic aperture radar (SAR) to retrieve ocean wave field parameters. Souyris’ and Nord’s algorithms are used to carry out the reconstruction of CP SAR pseudo quad‐polarized data for the ocean surface under both the circular transmit linear receive (CTLR) and ...

Synoptic Controls of Extreme Ice Area Flux Events Along Nares Strait

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Nares Strait, the channel between Ellesmere Island and northwest Greenland, connects the Arctic Ocean's Lincoln Sea to northern Baffin Bay. The transport of thick, multi‐year sea ice southward down the Strait contributes to the overall loss of this important ice class from the Arctic.

Comparisons of Circular Transmit and Linear Receive Compact Polarimetric SAR Features for Oil Slicks Discrimination

Journal of Sensors, Volume 2015, Issue 1, 2015., 2015
Compact polarimetric (CP) synthetic aperture radar (SAR) has proven its potential in distinguishing oil slicks and look‐alikes. Polarimetric information can be retrieved directly from scattering vector or from reconstructed pseudo‐Quad‐Pol covariance matrix of CP SAR data.

Identifying Thermodynamic Regimes of CO2 Gas Exchange During the Melt Transition on First‐Year Sea Ice Using a Multi‐Sensor Synthetic Aperture Radar Approach

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Few multi‐year observations of CO2 gas exchange exist over melting first year sea ice (FYI). We report 4 years of CO2 flux data during the melt season in Dease Strait, Nunavut, Canada. Utilizing a dried, closed‐path eddy covariance system on an island within the strait, we identify two statistically distinct CO2 flux melt regimes: a pre‐pond ...

Model‐Based Pseudo‐Quad‐Pol Reconstruction from Compact Polarimetry and Its Application to Oil‐Spill Observation

Journal of Sensors, Volume 2015, Issue 1, 2015., 2015
Compact polarimetry is an effective imaging mode for wide area observation, especially for the open ocean. In this study, we propose a new method for pseudo‐quad‐polarization reconstruction from compact polarimetry based on the three‐component decomposition.

Oil Spill Candidate Detection Using a Conditional Random Field Model on Simulated Compact Polarimetric Imagery

Canadian Journal of Remote Sensing, 2022
Although the compact polarimetric (CP) synthetic aperture radar (SAR) mode of the RADARSAT Constellation Mission (RCM) offers new opportunities for oil spill candidate detection, there has not been an efficient machine learning model explicitly designed ...
