Using WaveFarer Auto Radar Simulation and Chirp Doppler to Assess Radar Performance for Drive Scenarios

Introduction to Auto Radar Simulation

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 with chirp Doppler analysis algorithms to assess radar performance for drive scenario simulations.
