Comparison of commercial simulation performance for efficient RCS analysis

Radar design system and Stealth design system have been continuously developed. Radar cross section(RCS) is required in order to develop the systems, but it takes a lot of time for measuring RCS. Therefore, in general, M&S(modeling and simulation) is performed to predict target's RCS values. Nowadays, there are a lot of M&S for calculating RCS values such as WIPL-D, FEKO, HFSS-IE. Because each analysis method and performance simulation time for M&S tools is different, it is necessary to analysis the strength and weakness of each simulation. In this paper, we perform RCS M&S in the same environment using WIPL-D, FEKO and HFSS-IE, and compare the RCS data, simulation time and required computer resources in order to examine the reliability and efficient analysis for RCS.
