A Digital Sounder System for Single Site Location and Tactical Communication Needs.

Abstract

This report documents a technique to determine the ionospheric structure in real time. The study of ionospheric structure consists of electron density profile calculations and frequency management prediction charts. Until this time, no automatic system could evaluate ionospheric data. Analog sounders produced data which was evaluated manually and then processed off-line by large digital computers. This technique was expensive in terms of computer costs and also inefficient due to the fact that sounder routines could not be changed rapidly enough to adjust to varying ionospheric conditions.
