NUCOM/BREM. An Improved HF Propagation Code for Ambient and Nuclear Stressed Ionospheric Environments

Abstract

The NUCOM/BREM computer code extends the NUCOM II HF propagation code to include direct ray and groundwave propagation modes for airborne and ground- based communications links. Provision is made for user-supplied airborne antenna patterns for both vertical and horizontal polarizations, and for corrected horizontal noise-factors for airborne terminals. A variety of airborne antenna patterns are included and sample links are evaluated. This computer code greatly extends the usefulness of NUCOM II for the analysis of HF links employing airborne terminals and relay aircraft.
