Using ERS-2 SAR images for routine observation of marine pollution in European coastal waters.

摘要: More than 660 synthetic aperture radar (SAR) images acquired over the southern Baltic Sea, North and Gulf of Lion in Mediterranean Sea by Second European Remote Sensing Satellite (ERS-2) have been analyzed since December 1996 with respect to signatures marine pollution other phenomena causing similar signatures. First results our analysis reveal that seas are most polluted along main shipping routes. The sizes detected oil spills vary between 56 km2. SAR during descending (morning) ascending (evening) satellite passes show different percentages pollution, because this occurs night time is still visible on morning time. Moreover, we found a higher amount summer (April-September) winter (October-March). We attribute finding mean wind speed encountered all three test areas winter. By using an ERS-2 image area how reduction normalized backscattering cross section (NRCS) spill depends speed.
