Propagation studies at microwave frequencies by means of very short pulses

Microwave pulses with a duration of about 0.003 microseconds were transmitted over a 22-mile path from Murray Hill, N. J., to Holmdel, N. J., in order to determine the effects of the transmission medium upon such pulses. During “fading” periods multi-path transmission effects with path differences as great as 7 feet were observed, as well as some other effects. A microwave frequency of 4000 megacycles was employed.
