NTIA Task Force Measurement Report: Naval Air Test Center, Patuxent River, MD

Report ID
TM 87-123
August 01, 1987

This report documents the results of a special measurement task at the Naval Air Test Center, Patuxent River, Maryland. In documenting the spectrum usage for land mobile, radar and microwave systems at an active military base, the report serves as a reference for future improvements to spectrum management techniques and procedures.

Spectrum Resource Assessment of the Federal Government Fixed Service (Bands above 400 MHz)

Report ID
TM 87-127
September 01, 1987

This report documents a spectrum resource assessment of the bands allocated to the Federal Government fixed service above 400 MHz on a primary basis. The assessment identifies allocations, standards, channeling plans and technological trends pertaining to the Federal fixed service. Technical and policy issues are discussed as part of NTIA's long-range planning effort.

Coordination Requirements for Space and Aeronautical Telemetry Systems (2200-2290 MHz)

Report ID
TM 88-134
September 01, 1988

This report documents an analysis of the probability of interference from systems in the space services to aeronautical telemetry system using the 2200-2290 MHz band. These calculated results may be used to determine the coordination requirements for compatible operation between these systems, if a relaxation in the power flux density limits is adopted.

Spectrum Resource Assessment of Selected U.S. Government Space Services

Report ID
TM 88-136
September 01, 1988

This report describes the use of space services by the U.S. Government in support of NTIA's Long Range Plan for Management and Use of the Radio Spectrum. The report addresses national and international regulations as well as frequency allocations, current and future government use of the space services, and spectrum management issues.

Single and Aggregate Emission Level Models for Interference Analysis

Report ID
TM 89-139
March 01, 1989

This report describes analysis models and software packages developed for the assessment of single-entry and aggregate interference from terrestrial emitters into terrestrial or airborne victim receivers. The menu-drive computer programs provide user options for input/output computations, parametric representations, propagations models and emitter distributions. The flexibility in the scenario creation, parameter selection, and computation mode, renders the models applicable to a wide variety of EMC assessments and conditions. Model descriptions, technical formulations, user manuals, and sample runs are provided in this report.
