T1 LIGHTNING LOCATION AND ESTIMATE OF THE LOWER IONOSPHERE EFFECTIVE HEIGHT USING BY DISPERSION PROPERTIES OF TWEEK ATMOSPHERICS JF Telecommunications and Radio Engineering JO TRE YR 2012 FD 2012-12-12 VO 71 IS 20 SP 1897 OP 1908 K1 lightning location K1 Earth-ionosphere waveguide K1 monitoring of the lower ionosphere AB A new technique is suggested for finding the distance from lightning discharge and the effective height of the lower edge of ionosphere, which is based on the frequency dispersion of tweek-atmospherics (tweeks) propagating in the Earth-ionosphere waveguide in ambient night conditions. Examples are given of the distance evaluating from experimental records of tweeks with the help of suggested method (in the range 500 − 2500 km) and of the effective ionospheric height along the tweek propagation path. Accuracy is estimated of the height and distance derived by the proposed algorithm. PB Begell House LK https://www.dl.begellhouse.com/journals/0632a9d54950b268,4dc2e21502959124,6f1628dc628c3db7.html
