DTIC ADP013970: On Possibility of Schumann Resonance Observations within Industrial Area

Use of ADC with high resolution allowed us to embrace dynamic range both signal and powerful narrow-band interference and on this base to implement a compensative real-time algorithm for suppression of narrowband interference. The developed algorithm provides suppression of "wings" occurred due to incommensurability of a time interval of a signal that undergo to the spectral analysis and a period of a narrowband interference. Preliminary results of observations of extremely low frequency (ELF) natural electromagnetic background (Schumann resonance) performed within urban areas are presented in the paper. We demonstrate both possibilities of registration of average spectra of the Schumann resonance background signal and ELF-transients.
