Numerical study of pedestrian RCS at 76–77 GHz

This paper discusses about the findings of a radar cross section (RCS) study of human at 76-77 GHz based on full-wave numerical model simulations. The trade-off between simulation accuracy and computation efficiency is discussed. In general, simulating full-body scattering at 76-77 GHz requires a fairly large computation resource (memory and CPU time) due to the large size of average human in terms of wavelength as well as many different geometries of different body parts. Measurement RCS pattern is included to verify the accuracy of the simulation model. This study may provide clues to develop unique radar signatures of pedestrian at 76-77 GHz.
