download PDFAbstract. The Radar Cross Section (RCS) of fighter jet hold a lot of importance in determining its air superiority. Electromagnetic simulations can be performed by employing numerical methods such as MoM, ray tracing methods or Physical Optics. Configuration of the wing is an important factor in determining the overall RCS of the aircraft. The current study explores the RCS of canard as placed in Chengdu J-20. The parameters are varied, the models are created and the simulations are conducted for monostatic RCS using far field approximation over a continuous frequency range using Physical Optics in FEKO simulator. The trends in results are analyzed and promising configurations are identified.
