  • Author: Greg Skidmore

Drive scenario simulation can offer significant benefits for early testing of sensor designs and as a complement to operational road tests. Focusing on mm-Wave radar sensors, there are several challenges to simulation of a realistic automotive scenario like:
• 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 Remcom’s WaveFarer ® Radar Simulation Software to describe challenges, solutions, and recent R&D to address key aspects of the problem, including target scattering, multi-path and clutter, and micro-Doppler from motion such as the moving limbs of a walking pedestrian.
