Paper Abstract

Ship wake and oil slick signatures imaged by both multispectral ETM (enhanced thematic mapper) onboard Landsat-7 (L7) and multi-polarization SAR (synthetic aperture radar) onboard Radarsat-2 (R2) were analyzed in this paper. Spectral analysis used all the available band data together, not as an image but as a set of spectral features. Multipolarization imagery offers scattering information of the ground surface. Ship wake signatures were readily detected by local Hough transmission. Oil slicks are expected to benefit from spectral reflectance deviation from the background water color or phase differences between polarization channels. The appearance of ship wake in an area surrounded by oil slicks was also considered, although we have not yet conclusion at this moment. Comparing to our former efforts with polarized radar data only, the combined view by multispectral and multi-polarization sensors indicated detailed radiation and scattering characteristics of ship wake and oil slick signatures.
