Learn how Remcom’s WaveFarer® Radar Simulation Software uses ray-tracing to simulate virtual drive scenarios and predict radar returns as a system moves through an environment with vehicles, roadway structures, pedestrians, and other objects.
Drive scenario simulation can offer significant benefits for early testing of sensor designs and as a complement to operational road tests. However, focusing on mmWave radar sensors, there are several challenges to 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 presentation uses WaveFarer to describe these challenges, possible 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.
