Multi-path propagation over asphalt road surfaces at automotive radar frequencies is studied. A new expression for the reflection coefficient from asphalt which takes into account asphalt surface roughness is proposed. The classic two-ray method to take into account the multi-path is improved using antenna radiation patterns and the antenna tilt. A new method to estimate elevation of a reflector above road surface based on reflectivity variations is proposed.
