Using the cross-spectral phase to filter slicks in the ENVISAT ASAR wave mode product

摘要

An empirical filter has been developed that uses the phase of the ASAR cross spectrum to detect slicks in the ENVISAT ASAR wave mode product. The filter has been tested on a partition of a set of simulated ASAR cross spectra distributed by ESA. Results show that variations of the cross-spectral phase with wave number can effectively be used for detecting slicks in ENVISAT's wave mode product.
