This paper presents a comparison of predicted and measured radar cross sections (RCS) of complex metallic objects at 77 GHz. For computing the RCS, a ray tracing algorithm combined with physical optics and the incremental length diffraction coefficient is used. The simulated results are compared against measurements, obtained using a 77-GHz frequency-modulated continuous-wave radar sensor.
