Özet:

In this study, a MATLAB code incorporating `Shooting and Bouncing Rays (SBR) Method` is developed for calculating Radar Cross Section (RCS) of complex shapes. The code can calculate ray paths, magnetic current sheets, incident and scattered electric fields and RCS in horizontal, vertical and cross polarizations. While reflection effects are calculated by SBR algorithm, diffraction effects due to edges and corners are handled by `Equivalent Edge Currents (EEC’s)`. Wave frequency, aspect angle and number of rays are the input parameters of the code. Primitive geometries can be generated and analyzed by the code. In case of complex shapes, the input to the program is generated by 3D CAD tools in STL format. Several conclusions drawn from the calculation results are presented.
