May 1997 ISSN 1055-1425 FMCW MMW Radar for Automotive Longitudinal Control William David California PATH May 1997 1 FMCW MMW Radar for Automotive Longitudinal Control William David Overview This report develops introductory information on millimeter wave (MMW) radar for automotive longitudinal control. It addresses the fundamental capabilities and limitations of millimeter waves for ranging and contrasts their operation with that of conventional microwave radar. The report can serve as a primer or tutorial for researchers who are working in the field of automotive control and who may apply radar for headway and lane control studies during platooning operations. The report analyzes pulsed and FMCW radar configurations, and provides detailed treatment of FMCW radar operating at MMW frequency, its advantages and pitfalls as they relate to range and velocity measurements. Some of the material of this report can be found in texts and period
