Abstract:
This report serves as a test case manual for the DSI3D-RCS code, which is designed to numerically calculate radar cross sections (RCS) for complex objects by solving Maxwell's curl equations in the time domain. The code is optimized for parallel processing computers and is validated against a series of test cases, including a wedge cylinder, a NASA almond, and a wavelength circular cavity. To generate the results, the simulations perform backscatter calculations where the incident pulse angle is incrementally changed, requiring a separate run for each data point. The document presents the outcomes as graphical comparisons between the DSI3D simulation results and measured experimental data for both horizontal-horizontal (HH) and vertical-vertical (VV) polarizations at various frequencies. It also provides detailed input file parameters and mesh visualizations used for each specific test, demonstrating the code's application in solving complex electromagnetic scattering problems.
