ANALYSIS AND DESIGN OF A MADA DATA COMMUNICATION SYSTEM FOR METEOROLOGICAL/OCEANOGRAPHIC BUOYS.

Abstract

A signal design for use in the HF medium is developed and theoretically compared with other signal designs in current use. The use of matched filters is considered and several designs are shown as examples. Some advantages of discrete addressing of buoys are discussed and techniques of discrete addressing which are practical and compatible with the signal design are presented. The codes to be used for addressing and for data are discussed within the framework of Hamming distances and error detecting/correcting capability, and two specific sets of address codes are given. A system design using the described signal designs and addressing techniques is developed around the requirements, and key elements of the system design are presented and analyzed. It is concluded that HF telemetry of meteorological data from unmanned stations at sea is feasible and economically desirable under certain conditions and recommendations concerning system design and emission characteristics are made.
