M. E. Johnson and G. D. Gierhart, “Applications Guide for Propagation and Interference Analysis Computer Programs (0.1 to 20 GHz),” Sponsor Report FAA-RD-77-60, March 1978

This report covers ten computer programs useful in estimating the service coverage of radio systems operating in the frequency band from 0.1 to 20 GHz. These programs may be used to obtain a wide variety of computer-generated microfilm plots such as...

Arthur D. Spaulding and George H. Hagn, “Worldwide Minimum Environmental Radio Noise Levels (0.1 Hz to 100 GHz),” Conference Paper Unnumbered, January 1978

It is desirable to design receiving sys­tems so that the receiver will be close to being limited by external noise. Indeed, it is cost ineffective to design radio receiving systems with noise figures significantly less than the minimum values of the...

John P. Murray, “Needs for the Radio Spectrum and for Radio Spectrum Research,” Special Publication Unnumbered, January 1978

This report is an initial attempt to identify and emphasize needs for radio spectrum and for related spectrum research to serve as the basis for planning for Efficient Use of the Spectrum Program at OT/ITS. However, any need or requirement for spect...

Hans J. Liebe and Gary G. Gimmestad, “EHF Transfer and Shielding Properties of Air: Summary of 1974–1977 Activities,” Technical Memorandum TM-77-242, October 1977

This is the final report on work performed at the Institute for Telecommunication Sciences on “Atmospheric Transfer and Shielding Properties in the 50 to 75 GHz Band” (ARO Proposal NR. 12233 GS). The microwave spectrum of oxygen (02—MS ) was ...

R. D. Jennings and S. J. Paulson, “Communication and System Performance Model for VHF and Higher Frequencies,” Technical Report TR 77-128, October 1977

Communication system designers and engineers often must decide whether to use design-aid models not well suited to the problem at hand or to perform many tedious and laborious hand calculations which, coupled with certain “rules of thumb,” provide a...

Arthur D. Spaulding and George H. Hagn, “On the Definition and Estimation of Spectrum Occupancy,” Journal Article, August 1977

Spectrum occupancy for channels and bands of similar channels is defined. A distinction is made between transmission occupancy and message occupancy. The measurement time required to determine if a given channel is occupied is considered as well as t...
