Abstract : The steady state solution of the Maxwell Equations for wave propagation is interpreted in terms of a transfer function which described the ionosphere as a linear dispersive system. The effect of the ionosphere on signal transmission is obtained by inversion of a Fourier integral, and the relevance of group velocity, signal velocity, and time delay concepts is examined. The dispersion decreases the output signal of a typical UHF correlation receiver by less than 3db for normal ionospheric conditions. (Author)
