Abstract:
DoD test ranges are experiencing ever-expanding needs for air-to-ground telemetry bandwidth, and hence are under pressure to manage the telemetry spectrum resource with high efficiency. The Spectrum Management System SMS provides test range operations staff with advanced tools for frequency de-confliction and air-to-ground RF link quality prediction for upcoming test flights. Additional features of the system include automated, algorithm-based frequency de-confliction and assignment record-keeping and automated archiving of frequency assignments, to be used for spectrum defense 3-D GIS terrain-based coverage maps, displaying predicted air-to-ground link quality in each part of upcoming flights determination of opportunities for frequencies reuse. Innovations include addressing the combinatorial NP-hard problem of frequency assignment by applying multiple real-world constraints in a specified order using a spectrum white space closest-fit algorithm to minimize spectrum fragmentation creating space-time-frequency quanta in the database to store RF emissions for rapidly-moving aircraft.
