Large objects, such as ships, anechoic chambers, and aircraft, often require maintenance due to material defects. These defects must be repaired to maintain the desired Radar Cross Section (RCS). To avoid some of this maintenance, we propose to determine defect tolerances by simulating the RCS of such objects using the parallelized Finite-Difference Time-Domain Method (FDTD). Our presentation includes a discussion of the implementation of a parallelized FDTD method with MPI. We then discuss the implementation of parameter sweeps with the FDTD method to investigate the RCS of objects with added defects. Finally, we present preliminary results comparing pristine PEC, Dielectric, and Dielectric-Coated PEC spheres and flat plates to those with simulated defects of varying size.
