Drive scenario simulation can offer significant benefits for the early testing of sensor designs and as a complement to operational road tests.
Focusing on mmWave radar sensors, there are several challenges to the simulation of a realistic automotive scenario:
- Near-field conditions that invalidate traditional RCS concepts
- Densely-faceted vehicle models; complex for traditional “propagation” ray-tracers
- Complex multipath from roadside structures (guard rails, signs, parked vehicles, etc.)
- Dynamic scenarios with multiple vehicles in motion, potentially with moving parts
This white paper uses Remcom’s WaveFarer Radar Simulation Software to describe challenges, solutions, and recent R&D to address key aspects of the problem, including target scattering, multipath and clutter, and micro-Doppler from motion such as the moving limbs of a walking pedestrian.
