Benefits of Time-Domain Electromagnetic Simulation for Automotive Radar

Trends in automotive safety are pushing radar systems to higher levels of accuracy and reliable target identification for applications like blind spot monitoring and cross traffic alert. Consequently, the requirements for automotive radar sensors in frequency bands such as 24 GHz and 77 GHz are becoming more stringent and engineers need to better understand how design decisions affect performance.

Time-domain electromagnetic simulation promotes rapid development by allowing engineers to determine the performance of a fully detailed sensor model installed behind a piece of fascia without needing to build prototypes and run tests in an anechoic chamber. In this paper, the analysis of a 25 GHz sensor will be discussed using Remcom’s XFdtd Electromagnetic Simulation Software.
