Abstract

A continuous, self-supporting microwave transmission line along which ultra short pulses of microwave signals may propagate over distances of several hundred feet with minimum pulse distortion and signal attenuation. Propagation along the line is accomplished by an electromagnetic field thereabout that is sensitive to objects positioned in the proximity of the transmission line, a characteristic that may be utilized in short pulse reflectometer systems for monitoring and control of vehicles on a prescribed course.
