Abstract
An analytical solution to the problem of ultrashort radio pulse propagation in the gas medium with two isolated spectral lines, which is obtained without Fourier integral calculations and is not restricted by the path length or the selection of the a priori time dependence of the field strength of an emitted pulse, is presented. As applied to a ground path, this solution was used to consider possible behavior and features characterizing the distortions of a sinusoidal train and a rectangular quasi-monochromatic pulse, the spectra of which belong to the atmospheric transparency window restricted by frequencies of 326.4 and 380.1 GHz. The dependences between the integral characteristic of pulses and the carrier-frequency position with respect to boundary frequencies are analyzed.
