Abstract: | The computer Doppler filtering of a ground wave is proposed for diversity reception of signals from LF broadcasting stations
with a high-stability master oscillator. This method can be employed in round-the-clock measurements of the motion characteristics,
absorption, and angles of arrival of radio waves. The method was implemented in a LF receiving complex. First results on the
dynamics of ionospheric irregularities and radio wave absorption at ionospheric D-layer heights are presented.
