A hybrid method for computing the RCS of wire scatterers with an arbitrary orientation

Abstract

A hybrid method is proposed to compute the radar cross section (RCS) of multiple wire scatterers with an arbitrary orientation. Foldy-Lax equations in vector form are transformed into self-consistent equations for including the multiple scattering effects between scatterers. A thin-wire approximation of a method of moment (MoM) is used for calculating the scattering transition operator of a single wire scatterer. To verify the proposed method, two measurement models are fabricated and measured in a compact range chamber. The measured results agree well with the results of the proposed method.
