MONITORING OF THE RADIO-FREQUENCY SPECTRUM WITH A DIGITAL ANALYSIS SYSTEM: AN UPDATE

摘要

At the 15~(th) Wroclaw EMC Symposium a description was presented of a versatile Digital Analysis System (DAS) monitoring system. This high speed system, developed by the Communications Research Centre of Industry Canada, is now in use by the Canadian government for its radio spectrum monitoring program. This system is based on VXI-based "plug and play" Commercial Off The Shelf (COTS) hardware components. The control of equipment and all digital signal processing is done with the use of a personal computer (PC). The open system hardware and software architecture allows for facile changes to equipment hardware and monitoring application programs as compared to DSP based systems. The civilian version of this system is now called the Spectrum Explorer (SE). This paper describes new applications and changes to the SE system since the original presentation.
