LES-8/9 Spectrum-Survey Techniques

Abstract

Techniques for surveying the electromagnetic spectrum using communications satellites as sensors are discussed. The techniques presented are based on the use of tunable (by ground command) frequency synthesizers carried on Lincoln Experimental Satellites 8 and 9 (LES-8/9). The frequency synthesizers are used for first-downconversion local oscillator in the satellite uplink receiver. Repetitive commanding of these synthesizers combined with on-board selectable filter bandwidths, signal power detectors, and a high telemetry data rate are shown to constitute an effective spectrum analyzer. Interpretation and presentation of collected data are also discussed. This work was first reported at the Fourteenth Meeting of The Technical Cooperation Program (TTCP), Subgroup- S (Communications Technology and Information Systems) Technical Panel STP-6 (Space Communications) held at the Communications Research Centre, Ottawa, Canada, 26-30 January 1987.
