Abstract: This document describes techniques and systems for electromagnetic response simulation for arbitrary road surface profiles. An electromagnetic response simulator receives a position and an orientation of both an electromagnetic sensor (e.g., radar sensor) and a target, and a geometric profile of a road surface. The road surface may vary in elevation in the lateral and/or longitudinal directions. The electromagnetic response simulator estimates reflection points of electromagnetic rays along the geometric profile of the road surface and translates the positions and the orientations of the electromagnetic sensor and the target into respective local coordinates corresponding to each reflection point. The electromagnetic responses can then be calculated, corresponding simulated rays can be output to a sensor simulator. In this manner, the variance in elevation of a road surface can be included in generating simulated rays, and the electromagnetic response simulator may more accurately simulate real-world electromagnetic responses.
