Abstract
A technique is described of distance finding to sources of radio pulses (lightning discharges) concurrently with the height of the Earth–ionosphere duct. The approach exploits wave interference between different waveguide modes in the amplitude spectra of night atmospherics (tweeks). By using this technique the source–observer distances were found ranging from 500 to 4 000 km for an ensemble of experimental waveforms recorded in the Atlantic and Indian oceans. The ionosphere height variations were obtained from experimental data being 5–6 km during the night and having 2–3 km changes on seasonal time scale.
KEY WORDS:lightning location, Earth-ionosphere waveguide, lower ionosphere monitoring
