A Computer Program for ELF/VLF Pulse Propagation in a Laterally Homogeneous Earth-Ionosphere Waveguide

摘要

This report contains a computer program designed to handle pulse propagation problems when the propagation channel is the earth-ionospheric waveguide. The program is intended for use in the elf/vlf bands for laterally homogeneous channels. Mode data as a function of frequency from a waveguide program are required inputs to the present program. The mode data are interpolated using cubic splines, and the requisite integrals are treated numerically by means of the fast Fourier transform. (Author)
