Computer Programs for Assessment of Long-Wavelength Radio Communications, Version 2.0: User's Guide and Source Files

Abstract : This document describes a revision of the Navy's Long-Wavelength Propagation Capability (LWPC) developed by the Space and Naval Warfare Systems Center, San Diego. This version of the program includes improvements to the graphics routines, increased flexibility in specification of alternative ionospheric models, and an option to execute a full-wave mode conversion model for the signal-strength calculations. This version is principally composed of FORTRAN subroutines with a few additional routines written in C to implement the graphics capabilities under the Windows 95/NT operating systems.
