Abstract
The distortions of pulsed radio signals in passage through a dispersive medium with a quadratic phase function are examined. These distortions are determined quantitatively by the relative pulse broadening. Analysis shows that the degree of envelope distortion is determined by a single dimensionless parameter and is practically independent of the signal spectrum. This parameter, which is called dispersion disphasing over the spectral interval, is easily calculated and is very useful for estimation of the degree of radio-pulse broadening. An example of its use for the simple case of pulse propagation through a parabolic ionospheric layer is provided.
