Abstract
DRDC – Ottawa Research Centre is developing an experimental Over-the-horizon Radar (OTHR) with the potential for surveillance of the Canadian North. A Spectrum Management System (SMS) is a critical component of the OTHR, assessing the spectral environment and identifying portions of the High Frequency (HF) band of operation available for the system to use. In this report, the merging of two important sub-systems of the SMS, namely the merging of the Frequency Monitoring System (FMS) and the Ionospheric Condition Monitoring System (ICMS), was presented using a simulated commercial aircraft tracking exercise as a mission. The exercise involved tracking the Air China Flight CA990 commercial aircraft from New York’s JFK International Airport to Beijing’s Capital Airport, flying over Canada. Merging of the FMS and ICMS to form the SMS involves temporal matching and occupancy vector formatting before applying the Boolean function AND. The two main objectives of this experiment were met. The number of frequency channels available for this particular mission was determined for each 15 minute update. It was verified that options remained available over the full mission. The percentage of available frequency channels after merging the FMS and the ICMS over the entire spectrum varied from 0.35% to 1.07%. This mission exercise demonstrated that there is ample choice for OTHR transmitter operation and more options could be available by increasing ICMS frequency resolution. The ultim
