“…First experiments on C-band RADARSAT-2 full-polarimetric SAR data demonstrate the capability of the approach to highlight features that are polarimetrically different from the background sea in a broad range of sea state conditions and almost independently of look angle. In [7] and [8], a dual-polarimetric model to exploit reflection symmetry to observe metallic targets at sea is developed and successfully tested on C-band RADARSAT-2 SAR data. In [9]- [11], a polarimetric processing chain to observe both 0364-9059/$31.00 © 2012 IEEE oil slicks and man-made metallic targets in full-polarimetric SAR data is developed and successfully tested on both L-band ALOS-PALSAR and C-band RADARSAT-2 SAR data.…”

A dual-polarimetric model to exploit X-band COSMO-SkyMed (CSK) dual-polarimetric PingPong mode synthetic aperture radar (SAR) data for metallic target observation purposes is first developed. The model relates the correlation between the copolarized channels, in case of sea surface with and without metallic targets, to the time offset between bursts related to the HH and VV polarimetric channels. Following this theoretical rationale, a constant false alarm rate (CFAR) approach is implemented to first exploit CSK PingPong full-resolution SAR data for target observation purposes. Experiments undertaken over a large data set of COSMO-SkyMed single look complex slant (SCS) PingPong HH/VV SAR data demonstrate the physical soundness of the approach and its effectiveness from an operational viewpoint. A whole CSK SAR scene is processed in about 10 s. Furthermore, the dual-polarization approach is also compared with a conventional single-polarization CFAR one and it is shown to perform best.

“…Nowadays, the importance of the transmit-receive antenna polarizations on ship detectability is well-understood. Few physically-based polarimetric approaches have been developed to observe metallic targets at sea [1,2,3,4,5,6], supported also by new high-performances polarimetric SARs, e.g. the ones operated onboard of the ALOS, RADARSAT-2, TerraSAR-X and COSMO-SkyMed missions.…”

A dual-polarimetric model to exploit PingPong mode X-band full-resolution COSMO-SkyMed (CSK©) SAR data for metallic targets observation purposes is developed. The model relates the correlation between the co-polarized channels, in case of sea surface with and without metallic targets, to the time leg between two successive bursts. Experiments undertaken over COSMO-SkyMed Single Look Complex Slant (SCS) PingPong SAR data demonstrate the soundness of the proposed approach and its effectiveness from an operational viewpoint

“…With the advent of polarimetric SARs, new, effective, and automatic physical approaches have been conceived to locate and monitor oil spills [Gade et al, 1998;Migliaccio et al, 2011Migliaccio et al, , 2009aMigliaccio et al, , 2009bNunziata et al, 2011Nunziata et al, , 2010Nunziata et al, , 2008Velotto et al, 2011;Zhang et al, 2011]. These new approaches exploit the correlation characteristic between and among polarimetric signals when crude oil at sea is observed.…”

Polarimetric synthetic aperture radar utilized to track oil spills

The continued demand for crude oil and related petroleum products along with the resulting upward spiral of the market price of oil have forced oil exploration and production companies to seek out new reserves farther offshore and in deeper waters. The United States is among the top five nations globally in terms of estimated offshore oil reserves and petroleum production. Yet deepwater drilling to extract these reserves is a major engineering challenge for oil companies. Moreover, such drilling activity also comes with a significant environmental risk, and the extremely high pressures associated with deepwater oil wells mean that the mitigation of accidental releases from a deepwater spill is truly a challenging endeavor.
