  • Direction finder for ionospheric earthquake precursors

    Article is devoted to the creation of direction finders for bearing earthquakes ionospheric precursors. Structural diagrams of two direction finders variants are given, their advantages and disadvantages are shown. Algorithms for the direction finders functioning and selection of ionospheric precursors are developed.

    Keywords: radio direction finder, ionospheric earthquake precursor, signal selection, phased antenna array, wave, oscillation, phase, azimuth, angle of elevation
