Abstract
Simulation approach for investigating long-range automotive radar system under realistic road environment is presented considering 77 GHz band. The system features are validated using ray-tracing simulation under realistic 3D traffic environment. The developed approach incorporates every involved domain, starting from waveform generation to target detection considering all high-level effects of the system. A generic phased-array FMCW radar transceiver is considered based on 4-element uniform linear array (ULA) of microstrip patch antenna. The position and velocity information obtained from the developed automotive radar system has further been used for vehicle platooning. To increase the road traffic capacity based on platooning, both inter-vehicle communication and automotive radar are required. Thus, vehicular communication based on IEEE 802.11p DSRC band has also been investigated.
