User's Manual for NUCOM III. An HF Nuclear Effects Code Incorporating WEPH VI-Mod 1.

Abstract

This report is a user's manual for NUCOM III, a computer code that predicts the magnitude and duration of nuclear weapon effects on the performance of HF communication systems. NUCOM III consists of five components: NATPAT, WEPH, ORDER, RAYTRA, and COMEFF. These components operate sequentially to: compute an ionospheric model representative of the natural ionosphere along a path; compute an ionospheric model that accounts for the nuclear effects on the ionosphere along a path; include mechanical wave effects on the ionosphere; compute the characteristics of raypaths using a propagation model that does not restrict the type or number of raypaths that may exist; and combine the raypath characteristics at a frequency and time to obtain an estimate of the communication system performance. NUCOM III incorporates WEPH VI--Modification 1 as its second component; the previous version of NUCOM (NUCOM II) incorporated WEPH V--Modification 7. This report describes the changes made in the code to incorporate WEPH VI, and other modifications made in NUCOM since NUCOM II. (Author)
