Incoherent scattering analysis for radar clutter

This paper proposes a method to estimate directly the incoherent scattered intensity and radar cross section (RCS) from the effective permittivity of a random media. The proposed method is derived from the original concept of incoherent scattering. The incoherent scattered field is expressed as a simple formula. Therefore, the proposed method can estimate the incoherent scattered intensity and RCS of random media for reducing computation time. To verify the potentials of the proposed method for the desired applications, we conducted an additional the Monte-Carlo analysis using the method of moments (MoM), and characterized the accuracy of the proposed method using the normalized mean square error (nMSE). In addition, several medium parameters such as the density and analysis volume were studied to understand their effect on the scattering characteristics of random media. The results of the Monte-Carlo analysis show good agreement with those of the proposed method.
