Özet:The aim of this research is to analyze the variations in Radar Cross Section (RCS) values of dielectric and conducting objects due to material and shape uncertainties by employing the Finite Difference Time Domain Method and the Monte Carlo approach in electromagnetic scattering problems. MATLAB codes are developed and validated to solve the electromagnetic scattering problem involving two and three dimensional arbitrarily-shaped objects. Basic principles of FDTD and its implementation in MATLAB are described. Based on the two-dimensional FDTD code, the results of several Monte Carlo simulations are presented by varying the relative permittivity and the geometry of the object. Several conclusions are drawn by post processing the coherent and incoherent components of the RCS values. The results are compared with Method of Moments results and analytical results if available, and a good agreement among the results is observed.
