Propagation of a Rectangular Radio Pulse with a Chaotic Phase in a Resonance-Absorbing Gas Media

In this study, we analyze the possible nature and characteristics of dispersion distortions of a rectangular nanosecond radio pulse with a chaotic phase modeled based on a Chebyshev map of the first kind of the third order during propagation in a resonant-absorbing gas medium. The removal of the pulse from the emitter is shown to be accompanied by the transformation of the envelope to a noise-like form and the formation of its “tail,” which can account for a noticeable fraction of the current energy. It was established that, in a sufficiently wide range of parameter values ​​describing the degree of randomness of the instantaneous phase of the emitted pulse, the effect of the medium does not lead to the destruction or fundamental changes in the form of its correlation functions during the propagation process.
