Abstract:

An approximate but efficient technique is presented that accounts for vertical polarization and rough surface effects over the sea for ducting conditions using the split-step, parabolic equation method. The primary justification for this semi-empirical technique is that in most cases propagation loss predictions match results from a waveguide model that is believed to account for these effects properly. The technique and comparisons of modeled results versus waveguide results and measured data are examined.
