RCS computation and Analysis of target using FEKO

Radar engineers always have specific requirements for target's RCS data computation and Analysis. Target's detectability can be obtained by 1-dimensional probability density functions (PDF) and 2-dimensional RCS intensity. Based on varying angles of incidence and frequency of excitation RCS data, target's Inverse Synthetic Aperture Radar (ISAR) [1] image can be calculated by 2D-IFFT. In this paper, a missile's RCS is computed by FEKO, the RCS 1-dimensional PDF, 2-dimensional RCS intensity and ISAR image are presented. For the scattering characteristics of antenna, the structural mode scattering and the antenna mode scattering can be identified separately in FEKO. Owing to various CEM solvers and powerful abilities of postprocessing script, FEKO can be clearly used for RCS and radar research and development purpose.
