Abstract:

A computer program designed to handle pulse propagation problems when the propagation channel is the earth-ionosphere waveguide, and intended for use in the elfvlf bands, is presented. The program is intended for use with laterally homogeneous channels. Allowance is made for transmit and receive antennas of arbitrary elevation and orientation. Mode data as a function of frequency from a waveguide program are required inputs to the present program. The mode data are interpolated by using cubic splines, and the requisite integrals are treated numerically by means of the fast Fourier transform.
