Abstract

COBRA: a computer code for the backscattering analysis of complex objects R. Qrta, P. Savi, R. Tascone Dipartimento di Elettronica and CESPA (C.N.R.), Politecnico di Torino, Cor so Duca degli Abruzzi 24, 10129 Torino, Italy ABSTRACT The computer code COBRA for the computation of the backscattering Radar Cross Section (RCS) of arbitrarily shaped metallic objects is presented. The scatterer surface is specified through a set of data points and interpolated by bicubic splines in parameter space and the scattered field is computed in the Physical Optics approximation. A numerical integration technique for triangular and rectangular parametric sub domains, based on an algorithm with error control, is described. I Introduction An existing need in the electromagnetic community is for computer codes capable of predicting the Radar Cross Section of a complex object, such as an aircraft [1]. For computing the electromagnetic field scattered from objects that are large wi
