Radar cross section minimization analysis for different target shapes

Abstract

The continuous improvement and development of military application devices have led to the analysis of their stealth characteristics. The Radar Cross Section (RCS) is the calculation of a target reflective power. The reduction of the RCS of military aircraft allows its late detection to capitalize on elements of security. The RCS of a military vehicle has thus become an extremely significant design element for security, effort and survival. Accurate RCS estimation and RCS reduction are therefore extremely essential for such type of vehicle. Numerous factors affect RCS, such as the target's form, orientation, operating frequency, aspect angle, the medium's permittivity and permeability, and the pulse's transmitted power. This paper aims to provide an overview of the theoretical history and engineering approach to the RCS estimation and reductions for such applications.
