VERIFICATION TECHNIQUES FOR SPECTRUM USAGE IN SPACE, TIME AND FREQUENCY

A Spectrum Usage Measurement System (SUMS) characterizes the actual use of telemetry spectrum at DoD flight test ranges. The system tracks daily usage in a measurements repository, which becomes an invaluable resource, allowing querying, reporting and analytics, for defending against future spectrum sell-offs, and for providing insights into improving spectrum efficiency. The question is how do we quantify spectrum usage in space, time and frequency? And how do we certify “actual usage”, as opposed to simple assignment and claims that the spectrum was planned to be used? We discuss techniques for addressing these challenges. The system draws upon spectrum mission planning data, a network of sensors of various types, and a correlation algorithm. A scaling problem wrt characterizing the spatial extent of the spectrum usage is solved. Correlation, using heterogeneous data sources at a test range with numerous RF emissions prompts a heuristics and flexible rules-based approach.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
