Scattering-based I/Q signal simulation of sea clutter returns

A fast Slope Summation Facet Model (SSFM) that derived from the original Bass and Fuks´ two scale model (BFTSM) is proposed to describe the sea scattering including both the coherent and diffused incoherent features. This kind of facet implement can readily change the average line budget of sea return locally corresponding to the facet returns, so that it can be used to find the amplitude of each scatterer. Moreover, with the help of the approximate phase extraction procedure, the coherent radar sea clutter could be readily obtained, which easily leads to the final realization on the modeling of the radar return data of I/Q signal.
