Purposes for this are better objective detection and identi cation in road tra c. This example shows how to model a 77 GHz 2x4 antenna array for Frequency-Modulated Continuous-Wave (FMCW) radar applications. Moormann Institute of Flight System Dynamics, RWTH Aachen University, Germany. The proposed solution again being subject of additional restrictions (time and overall number of sen-sors limited). The radar signal is characterized by a transmitted polarization of the radar signal. This paper introduces the radar and shows the result of a field test. The 77GHz devices also benefit from benefit from higher permitted transmit power. 4 and 5 GHz, allowing higher data rates .
