Sea clutter encountered in littoral environments
Authors: K. D. Ward and R. J. A. Tough
An analysis of low grazing angle open ocean sea clutter, based on a simple characterisation of the clutter in terms of scattering from ripples riding on long waves (the composite model) and from breaking waves, is extended to clutter encountered in littoral environments. The modelling of the scattering itself is unchanged; modification of the sea surface waves by limited fetch, wave refraction, current variations and enhanced breaking in shallow water affect the scattering structures significantly. Here we characterise the phenomena involved through relatively simple physical models that allow complicated and realistic environments to be modelled.
