Oil Spill Detection and Mapping |
The presence of oil on water reduces the
back scatter over the area of the spill
due to the attenuation of the Bragg
scale waves and a reduced signal
return to the sensor. On the iamge, the
oil spill has a darker tone than the
surrounding water. Wind shadows near
land, regions of low wind speed, natural
surfactants, and grease ice can be
mistaken for oil spills and ancillary or
multi-temporal information is
sometimes needed to discriminate the oil
spill from other phenomena. Steep
incidence angles are recommended for oil
spill detection. |
