Radar cross section simulations of arbitrary shapes

Abstract

This thesis is about the Radar Cross Section measurements of arbitrary shapes. The progress in radar cross section measurements is strongly related to the progress in Radar technology. Arbitrary shapes, such as aircrafts, vegetation, play important role in the application of Radar technologies. Furthermore, the electromagnetic scattering from dielectric objects has received increasing attention. Different disciplines are interested in different properties of the dielectric objects, and many published papers about this topic are found in literature. Firstly, RCS of simple shapes, such as flat plate, cylinder was measured and compared with the result given in the literature. Measurements were done in İstanbul Technical University in Electromagnetic Diagnostic and Measurement Laboratory for Vertical Polarization. On the other hand, Ansoft HFSS simulation program was used to complete RCS Measurements both simple and arbitrary shapes. RCS of arbitrary shapes that were obtained from hollow cylinder was calculated by using Ansoft HFSS to verify Discretization Solution. Lastly, RCS of complex shapes was computed. To compare with theoretical result, MATLAB programming is used. The good agreement were found for both Horizontal and Vertical polarizations for single layer models.
