Comparison of measured and predicted bistatic scattering from a right-angle dihedral

The bistatic radar cross section of a dihedral at three different orientations is measured and compared to five scattering predictions-method of moments (MoM), finite integration technique (FIT), shooting and bouncing rays (SBR), and two analytic models-closed-form PO (CPO) and a simplified parametric model. For many applications, accurate predictions in the mainlobe response are of most importance. We show that bistatic CPO and PM predictions have good fit to measured data in the mainlobe and are computationally more efficient than the numerical prediction methods.
