Significant innovation is taking place in automotive industry around capabilities for advanced driver assistance systems (ADAS). Radar sensors operating at millimeter wave bands are a key technology and require new modeling and simulation tools to predict their performance in driving environments.
Simulation of radar in realistic automotive scenarios poses several challenges:
Near-field conditions that invalidate traditional RCS concepts
Densely-faceted vehicle models are too complex for traditional propagation ray-tracers
Complex multipath from roadside structures (guard rails, signs, parked vehicles, etc.)
Dynamic scenarios with multiple vehicles in motion
This presentation demonstrates a new modeling and simulation capability that addresses these challenges, combining ray-tracing and scattering simulations from Remcom’s WaveFarer Radar Simulation Software with chirp Doppler analysis algorithms to assess radar performance for drive scenario simulations.
