Phase Variations of Kilometric Radio Waves Associated with Modification of the Ionosphere by High Power Radio Waves
Quasi-periodic variations in the phase of kilometric radio waves have been detected to occur at the distance of 1000 km from the “Sura” facility emitting high power, high-frequency radio waves. The main feature of the experiment was the appearance of quasi-periodic variations far away from the facil...

oai:ri.kharkov.ua:article-5022012-11-16T14:06:15Z Phase Variations of Kilometric Radio Waves Associated with Modification of the Ionosphere by High Power Radio Waves Фазовые вариации километровых радиоволн, сопутствовавшие воздействию на ионосферу мощного радиоизлучения Chernogor, L. F. Quasi-periodic variations in the phase of kilometric radio waves have been detected to occur at the distance of 1000 km from the “Sura” facility emitting high power, high-frequency radio waves. The main feature of the experiment was the appearance of quasi-periodic variations far away from the facility antenna pattern. The amplitudes of phase variations reached 5÷6°,and the variation period was equal to both the duration of stimulation (5 min) and the duration of the interpulse period (5 min). The amplitude of the phase variations was used to estimate the relative amplitude of the electron density disturbance, which reached 10 %. On reference days, the r. m. s. value of the phase variations never exceeded 0.5°, and the relative fluctuations in electron density were equal to 1÷3%.The observed effect cannot be explained by the acoustic-gravity waves generated by the periodic heating of the ionosphere. It most likely involves coupling in the Earth–atmosphere– ionosphere–magnetosphere system. Обнаружены квазипериодические вариации фазы километровых радиоволн, сопровождавшие воздействие на ионосферу радиоизлучения удаленного на расстояние около 1000 км мощного стенда “Сура”. Особенностью эксперимента было то, что квазипериодические возмущения возникали далеко за пределами диаграммы направленности антенны стенда. Амплитуда фазовых вариаций достигала 5÷6°. Период этих вариаций равнялся длительности воздействия (5 мин) и продолжитель- ности пауз (5 мин). По амплитуде фазовых вариаций оценена относительная амплитуда возмущений концентрации электронов. Она достигала 10 %. В фоновые дни среднеквадратичное отклонение фазовых флуктуаций не превышало 0.5°, относительные флуктуации концентрации электронов составляли 1÷3%. Наблюдаемый эффект не удается объяснить генерацией акустико-гравитационных волн периодическим нагревом ионосферной плазмы. Скорее всего, эффект связан с взаимодействием подсистем в системе Земля – атмосфера – ионосфера – магнитосфера.
