Обнаружение перемещающихся ионосферных возмущений в квазипериодических вариациях мощности некогерентно рассеянного сигнала

Abstract

Time intervals with incoherent scatter signal power varying quasi-periodically with periods of 5 – 120 min at altitudes between 100 km and 400 km are detected. Assuming these variations are caused by passage of travelling ionospheric disturbances, their parameters are estimated. Using a 663 s transmitted pulse is shown to result in overestimation of vertical phase velocity of wave processes аt low altitudes
