Antenli büyük platformların EM simülasyonları: RKA, anten yerleşimi ve radyasyon riski

The main purpose of this work is to study and investigate the electromagnetic properties of large platforms with and without antennas. Radar cross section (RCS), antenna patterns, mutual coupling and radiation hazard are the topics of interest. In this work, the concept of Radar Cross Section is studied by analyzing several canonical geometries and two vessels. Followed by this initial study, RCS simulations of a tank as a large platform, for a frequency range involving radar frequency bands up to Ka band have been performed by using the implementation of the Physical Optics (PO) Method by FEKO (A commercial software by EM Software & Systems-S.A. Ltd. (EMSS-SA).). Moreover, some approaches to reduce RCS of large platforms have been investigated and applied to the tank. After RCS analysis, a linear antenna has been modeled with simulation software EMSS-SA FEKO, ANSYS Inc. HFSS, and Computer Simulation Technology AG. MICROWAVE STUDIO. The antenna model has been analyzed with Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM), and Finite Integration Technique (FIT) for antenna parameters. A placement scenario on a large platform for a pair of the antenna of interest has been offered. Lastly, a large platform with antennas has been investigated for Hazards of Electromagnetic Radiation to Personnel (HERP).
