The use of resonance radio wave absorption by atmospheric oxygen to shorten nanosecond radio pulses
Abstract
The paper presents the results of an investigation of the envelope evolution of a trapezoidal nanosecond radio pulse propagating into the terrestrial atmosphere when the carrier frequency is in the vicinity of oxygen absorption bands at 60 or 118.83 GHz. Consideration is given to variations in the signal spectrum determined from propagation measurements. The possibility of obtaining significantly shortened pulses with an envelope shape only weakly dependent on distance during further propagation is demonstrated.
