This study is concerned with the development of a radar reflective patch to be used with a look-ahead radar in a convoying application for ground vehicles. The system considers a vehicle following configuration where the leader vehicle has a radar patch attached to its rear and the follower vehicle has a radar transmitter/receiver which obtains headway and orientation information by tracking the radar patch. The headway and orientation information is then conveyed to an onboard controller for automatic speed and steering control of the follower. The study has a number of different aspects including
development of a frequency selective surface for the patch
development of the radar system for determination of spacing and orientation
analysis and development of the control system for speed and steering control in a vehicle following configuration.
