Abstract :
A Doppler radar unit has been added to a remotely controlled automobile for automatic control of steering. This Doppler-type unit causes the vehicle to turn toward areas of minimum reflectivity, areas usually smooth with low vegetation. The vehicle with this steering system is shown to avoid all obstacles such as trees, automobiles, and people.
