Abstract

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.

具有共振相的矩形无线电脉冲在共振吸收气体介质中的传播

摘要

在这项研究中，我们分析了在共振吸收性气体介质中传播期间，基于第一类三阶切比雪夫图建模的具有混沌相位的矩形纳秒级无线电脉冲的色散畸变的可能性质和特性。示出了从发射器去除脉冲伴随着包络线转变成类似噪声的形式并形成其“尾部”，这可以占电流能量的显着部分。可以确定的是，在描述所发射脉冲瞬时相位的随机程度的足够宽的参数值范围内，介质的作用不会导致其相关函数形式的破坏或根本变化在传播过程中。
