Abstract
Method and apparatus are disclosed for communication of infrastructure information to a vehicle via ground penetrating radar. A vehicle comprising an antenna positioned to broadcast radio waves below the vehicle, a ground penetrating radar system, and an active safety module. The ground penetrating radar system determines types of reflectors and a spatial relationship between the reflectors based on radar cross-sections detected by the antenna, and generates a signature based on the shapes and the spatial relationship. The active safety module determines environmental data based on the signature, and autonomously control the vehicle based on the environmental data.
