In this paper, the design, analysis and numerical results of back scattering field of winged almond model with ammunition and without ammunition are presented. Simulations with using Physical Optics (PO) method in Ansys HFSS software for monostatic Radar Cross Section (RCS) were made in 1 GHz and 9 GHz. By using PO method to obtain the total scattered field received part of the radar, the body of the target is seperated into number of facets, then all these facets scattered field components are super imposed. When 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 winged almon model with ammunition on RCS are compared in different frequencies.
