Analytical Study of Bi-Static Radar Cross Section with a Comparison at S Band and X Band of F-117 Nighthawk Stealth Aircraft

Abstract

F-117 Nighthawk Stealth Fighter Jet is the world’s first true ‘Stealth’ aircraft that has low Radar Cross Section (RCS). Varying two of the most important parameters of RCS such as frequency of the radar transceiver and aspect angle, the best outputs are recorded as the results. Using COMSOL Multiphysics software a virtual chamber has been created and the CAD model of F-117 is applied in it. In this paper, the bistatic RCS calculation method is done for simulation. The results clearly depicted that RCS can be obtained better at higher frequency of S band and X band wave range and at some specific aspect angles the results exhibit higher detectability.
