Sea clutter measurement with airbone synthetic aperture radar

In this paper, we consider the surface motion as an important factor governing behaviours of the sea clutter observed in SAR images. Therefore, we propose a model for SAR - acquisition of time varying scenes. Then we derive from this model the 2nd order statistical properties of an acquired scene in terms of a time - dependant reflectivity q. We also introduce the sea surface elevation and we complete the reflectivity description by applying small slope approximation (SSA) of the wave scattering from rough surface.
