The sea area shown in this ERS-2 SAR image has an extent of 14.5 km x 9.7 km and lies in the frame shown above. In the upper right-hand corner a ship followed by a long turbulent wake is visible. At a distance of 1-3 shiplengths behind the ship the wake is associated with increased sea surface roughness. Further away from the ship the turbulence causes damping of the short wind waves (Bragg waves) and thus a reduction of the backscattered radar power. This is a typical SAR image of a ship`s turbulent wake.
