MIT researchers from the Computer Science and Artificial Intelligence Lab, or CSAIL, were able to develop technology that can help autonomous vehicles navigate through adverse weather conditions.
Where most autonomous vehicles navigate using a combination of LIDAR sensors or cameras, this system is able to allow the vehicle to 'see' through detailing what is under a road using a Ground Penetrating Radar, or GPR. GPR functions through sending out an electromagnetic pulse into the ground, this signal can determine the makeup of the ground under a road. Data about the ground underneath the road is then used in a map for the vehicle.
Teddy Ort, a Ph.D. student at CSAIL spoke about the project, "But LGPR can quantify the specific elements there and compare that to the map it's already created, so that it knows exactly where it is, without needing cameras or lasers."
