Feasibility Study of Bandwidth Reduction Technique for LORETS System

Abstract

The purpose of this feasibility study and test demonstration was to conduct analysis for a bandwidth reduction technique to be incorporated in a LORAN Retransmission (LORETS) System. The design concept resulting from the analysis was then breadboarded and tested in the laboratory to prove out the feasibility of using a bandwidth reduction technique with a LORETS System. The analysis that led to the original design concept is presented in this report. The breadboard bandwidth reduction system is also presented with results of this system with simulated LORAN signals, with the system hard wired at the down converted spectrum, and with the system over a hard wired RF link using LORAN C signals.
