Radar RCS estimation of a perfectly conducting Sphere obtained from a spherical polar scattering geometry

Stealth Technology plays a major role in order to make the targets unseen by enemy Radar. In Stealth Technology there are many signatures to be managed for a target in which most Radar systems use RCS as a means of discrimination of targets and classification with regard to Stealth‥ In this paper Radar Cross Section of a Sphere is computed with respect to the parameters like size and frequency. In this RCS has been computed using Mie scattering series in which the relation was given by Kerr[1]. The analysis given is based on spherical polar scattering geometry in which ans and bn^s are defined. The physical interpretation of ans and bn^s coefficients aids in visualizing the mechanism of the scattering process. In this paper, not only the RCS of a Sphere is computed at different frequencies with particular diameter but also the RCS is computed for various diameters at different band of frequencies. RCS treatment in this paper is based on Radar frequencies ranging from 0.1 Ghz to 40 Ghz.
