XFdtd simulation of a 24 GHz sensor mounted in the rear bumper of a sedan provides the framework for the discussion in this paper.

Trends in automotive safety are pushing radar systems to higher levels of accuracy and reliable target identification for blind spot detection and collision prevention assistance.  Consequentially, engineers need to better understand how mounting brackets, fascia, paint color, and bumper assemblies affect the far field radiation patterns of 24 GHz and 77 GHz automotive radar systems. 

Efficient FDTD EM analysis, combined with dramatic computation acceleration via MPI + GPU technology, make Remcom’s XFdtd an optimal choice for high-fidelity analysis of antenna-in-system designs that include both the 24 GHz antenna package and the automobile body features surrounding the device.  This whitepaper discusses these advantages using an EM simulation example of a radar mounted in the rear bumper of a sedan.
