Abstract: УДК 550.388:520.16: 520.8+534.29 Представлены результаты эксперимента, проведенного в 2006 г. Львовским центром Института космических исследований (ЛЦ ИКИ) и Институтом ионосферы (г. Харьков) по исследованию реакции ионосферы на акустическое воздействие. В качестве источника акустического сигнала использовалось оборудование ЛЦ ИКИ, установленное на территории Ионосферной обсерватории Института ионосферы. Диагностика изменений в ионосфере осуществлялась радаром некогерентного рассеяния с зенитной антенной и ионозондом “Базис” Института ионосферы, а также контрольной аппаратурой ЛЦ ИКИ. Обнаружены изменения параметров ионосферы на высотах 160 ÷ 200 км, следовавшие за воздействием на атмосферу акустического сигнала. Ключевые слова: акустическое воздействие, ионосфера, метод некогерентного рассеяния, метод вертикального зондирования Статья поступила в редакцию 15.10.2014 г.

TL;DR: In this paper, a low-noise uncooled heterodyne receiver was designed and constructed for measurements of the atmospheric ozone spectral line at 142.2 GHz, which has shown the double-sideband (DSB) receiver noise temperature of about 350 K within 130 to 150 GHz.
Abstract: A low-noise uncooled receiver was designed and constructed for measurements of the atmospheric ozone spectral line at 142.2 GHz. The design has shown the double-sideband (DSB) receiver noise temperature of about 350 K within 130 to 150 GHz. Critical construction features of the basic units (mixer, intermediate frequency amplifier, and diplexer) are described. Noise characteristics showed by the receiver are the best in the class of uncooled heterodyne receivers of the 2-mm wavelengths.

TL;DR: In this paper, the authors discuss the effect of different types of features on the quality of the results of the experiments and propose a method to improve the performance of the test data.
Abstract: Статья посвящена анализу влияния увеличения скорости солнечного ветра на возникновение геомагнитных возмущений. Значения скорости солнечного ветра, определенные из наблюдений мерцаний на радиотелескопах УТР-2 и УРАН-2 в 2003–2011 гг., анализируются совместно с параметрами солнечного ветра на уровне орбиты Земли и геомагнитными индексами . p A Повышение скорости солнечного ветра в периоды наблюдений было связано преимущественно с высокоскоростными потоками из корональных дыр. В феврале 2011 г. в период наблюдений имела место солнечная вспышка X-класса, сопровождавшаяся корональным выбросом массы. Установлено, что в рассматриваемые периоды времени геомагнитные возмущения возникали при отрицательных среднесуточных значениях перпендикулярной к плоскости эклиптики компоненты межпланетного магнитного поля. Обнаружено, что увеличение скорости солнечного ветра, которое наблюдалось на УТР-2 и УРАН-2 в широком диапазоне гелиоширот, сопровождалось увеличением геомагнитного индекса p A и возникновением геомагнитного возмущения. В то же время увеличение скорости солнечного ветра в узкой полосе гелиоширот вблизи плоскости эклиптики не сопровождалось геомагнитными возмущениями.

TL;DR: The experience of development of a digital receiver/pulse analyzer is described and is perfectly suitable for usage in radiolocation, radioastronomy, spectroscopy, in the systems for radioemission monitoring and in within the measuring-calibrating equipment.
Abstract: The experience of development of a digital receiver/pulse analyzer is described. The measuring set has a modular structure and consists of three functionally independent systems: Radio Frequency Tuner, Digital Pulse Analyzer, and Data Record and Storage System. The ultra-wideband Tuner operates within 0.4 to 18 GHz. The high performance Pulse Analyzer detects up to 2 million pulses per second in real time. The Data Recording System is capable of recording raw data and results of processing for as long as 40 min at the rate of up to 3 GB/s. This measuring set is perfectly suitable for usage in radiolocation, radioastronomy, spectroscopy, in the systems for radioemission monitoring and in within the measuring-calibrating equipment.

Abstract: Fields in bicone line and in free space are presented in the form of expansion over frequency-independent modes. Each mode possesses the dispersion depending on radius. With the mode matching method, the bicone antenna pulse radiation is calculated. It is shown that introducing some dielectric layer improves the antenna characteristics and allows to obtain the radiated field with higher amplitude.
