PRPSIM (Properties of Radio Wave Propagation in a Structured Ionized Medium)-A FORTRAN Code to Calculate Properties of Radio Wave Propagation in a Structured Ionized Medium. Volume 2. Theory and Models.

摘要

This report describes the PRPSIM (Properties of Radio Wave Propagation in a Structured Ionized Medium) code; a FORTRAN computer program for use in evaluating electromagnetic propagation effects resulting from detonation of nuclear weapons on satellite communications and radar systems. The code uses nuclear environment data files created by the SCENARIO high altitude, multiburst nuclear phenomenology code. PRPSIM calculates propagation effects due to enhanced mean ionization levels (e.g. absorption, noise, refraction, phase shift, Doppler and time delay variations, etc.). The code is written in ANSI FORTRAN-77 and has been installed and run on VAX, CDC/CYBER, ELXSI/EMBOS, and CRAY-1 computer systems. Volume I of the report is a user's guide which describes code installation, input, output, structure, and application. Volume II describes the underlying propagation effects theory and computational models. (jhd)
