In this paper, the analysis and numerical results of back scattering field of armed and unarmed Unmanned Air Vehicle (UAV) are presented. Simulations using Physical Optics (PO) method in Ansys HFSS software for monostatic Radar Cross Section (RCS) were made in 1 GHz, and 9 GHz. Since the electrical size of the target is twice as large as the wavelength, the order diffraction field is not considered. The fractured area from the first order will be sufficient to calculate the RCS of the target. Effects of ammunition quantity of modeled UAV with ammunition on RCS are compared in different frequencies.
