Forward-looking radar navigation system for 1997 AHS demonstration

A forward-looking chirp monopulse radar has been developed for road-vehicle guidance and collision avoidance. The radar chirps between 10 and 11 GHz and operates in conjunction with a frequency selective surface stripe laid in the middle of the highway lane. The monopulse guidance concept derives lateral position data from two receive antennas, one left and one right of the transmitter. The radar system is described in detail, and measured performance data are presented. This radar has been successfully demonstrated at the 1997 National Automated Highway System Consortium Technical Feasibility Demonstration on I-15 in San Diego, California.
