Abstract

Propagation characteristics for inter-vehicle communication using the 76-GHz band are measured. Direct waves and one-time wave reflection from the road surface are dominant factors affecting inter-vehicle millimeter-wave communication systems. The interference between direct waves and reflection waves causes considerable fluctuation in the received power. The vehicle vibration can be ignored with regard to its effect on millimeter-wave propagation. Attenuation by rain is another factor affecting signal propagation for intervehicle millimeter-wave communication. The attenuation caused by raindrops is especially great near the road surface because of the rebound of raindrops. These results will be useful for determining the link budget of inter-vehicle communication systems using the 76-GHz band.
