<p align="justify"> The integrated design approach is a very important approach, especially in the design process of a complex system such as airborne vehicle. Over the last few years, Radar Cross Section (RCS) experts were only involved in the final stages of the design process. This often results in the final design result having no expected RCS value, so that it affects the stealth characteristics of airborne vehicle that determine the survivability and reliability of airborne vehicle in carrying out missions. <br /> <br /> In this final project, numerical simulation is conducted using FEKO software to analyze RCS of airborne vehicle, with the case study in the form of missile. The goal is to understand RCS phenomena better on simpler model. Simulations were performed with variety of frequencies, measurement methods, coating materials and computational methods used to examine the comparative RCS values, the effectiveness of computational methods, and the computational requirements needed. <br /> <br /> From the simulation results, it can be concluded that FEKO can model and estimate RCS of complex geometry as well as RCS from coated geometry well. Physical Optics method can be applied to high frequency simulations effectively. The polar RCS diagram pattern formed from the high frequency simulation result using Physical Optics is close to the pattern using Method of Moments and Multi Level Fast Multipole Method. From the validation conducted, there is difference of 1.67 dBsm to 3.55 dBsm between the experimental result and simulation result in the measurement of monostatic RCS with frequency of 10 GHz. So, it can be concluded that the result of RCS simulation with FEKO software is close to the actual result as expected. <p align="justify">
