Abstract:

This report considers instrumentation for a proposed transoceanic duct propagation measurement program. In general, the ANFRC-56 communications system will supply most of the essential, and most costly, components of a system having the recommended sensitivity for an evaluation of the communications reliability of the trade wind inversion as a transoceanic duct. The modifications and additions to the FRC-56 system which are described will allow this system to be used for the quantitative measurement of transmission loss and bandwidth as a function of time. The system proposed in this report does not require any components or system design principles which are beyond the present state-of-the-art. Author
