But you were using radar for terrain mapping. Self driving road cars use cameras to follow lanes and radar to detect obstacles and other vehicles. Normal radar based adaptive cruise control you can buy in the majtory of je car brands today will do 180 kph (110 mph) and pick up other cars from over 200m away. So I think that setup is very different from the terrain mapping you were trying to do?
