Abstract:
During research focusing on radio frequency field transmission detection from broadcasters on known frequencies at known time and transmission in the magnetic field, anomalies were detected in frequencies outside of the frequency scope of the original research. Analysis of these anomalies indicated they were linked to an ongoing power issue in which a fuse had failed in a power transformer located approximately 1.3 miles from the magnetic field sensor system and antenna. The research crew, through the use of digital signal processing software, were able to diagnose the problem and assist electrical crews with fixing the issue while observing the anomaly at a distance that typically would be outside of the range of detection. The results supplemented previous research indicating magnetic field behavior is dissimilar to companion electronic field behavior during propagation by demonstration the collection of the magnetic field from an RF broadcaster located within a Faraday cage. The magnetic field was collected for analysis while the RF was undetectable. This incidental researched supported the potential for use of magnetic fields in remote sensing and remote classification of electronic activity. Further data analysis, including a meta-analysis of previously conducted studies which also produced anomalies validated that at a distance the magnetic field may be a viable candidate remote sensing of electrical activity, such as power outages, or radio frequency activit.
