This paper studies the accuracy and limitations of different electromagnetic (EM) simulation approaches for dielectric radar benchmark targets. In comparison to perfect electric conductors (PEC), dielectric targets are much more complex from an EM point of view. However, dielectric materials are widely used for modern aircraft and unmanned aerial vehicles (UAVs). Apart from that, EM simulation tools nowadays play an important role in the design of aerial vehicles and radar systems. In order to evaluate the accuracy and performance of different EM simulation approaches, the results obtained using Physical Optics in combination with a ray tracing approach are compared to full-wave reference data.
