Requirements for next generation automotive radars

Active safety is one of the most dynamic emerging topics in the automotive industry. Radars currently play a major role in providing sensing capabilities required to meet active safety requirements. Requirements, parameters, and characteristics of automotive radars change as a function of the operation range. The main goal of this work is to summarize sensing requirements of both short- and long-range automotive radars and to highlight present challenges to both systems. This work discusses various aspects of automotive radars, states their main challenges, and suggests possible solutions.
