Bistatic radar clutter simulations using scattering phenomenology

Most models used by the radar community for clutter simulations are empirical and intended for monostatic radars. For bistatic applications, the monostatic-bistatic equivalence theorem of Crispin, Goodrich, and Siegel (1959) is often used to estimate the bistatic clutter. We found that this theorem has serious limitations when applied to simulating scattering from clutter scenes. To address this issue we have developed a phenomenology-based model for efficient simulation of scattering from clutter scenes. The underlying algorithm is founded on a multiple scattering wave theory for a random medium layer over a two-scale rough surface. It works equally well for monostatic and bistatic applications and is computationally efficient and suitable for radar simulation studies.
