   <abstract xml:lang="ru">
    <p>В работе представлен метод интерпретации данных наклонного зондирования ионосферы (НЗ) непрерывным ЛЧМ-сигналом. Разработаны и реализованы гибридные алгоритмы автоматической интерпретации ионограмм по выделенным в результате вторичной обработки данных точкам со значимой амплитудой для различных гелиогеофизических условий. Для условий двуслойной ионосферы разработан метод интерпретации на основе анализа гистограмм распределения точек со значимой амплитудой, попадающих по задержке сигнала в модельную маску, построенную по результатам моделирования дистанционно-частотной характеристики мода распространения, при ее перемещении по ионограмме. Для многослойной ионосферы интерпретация проводится на основе исследования амплитудного рельефа ионограммы. Отдельно рассматриваются алгоритмы выделения треков сигналов, отраженных от спорадических слоев. Приведены результаты интерпретации ионограмм, полученных на сети радиотрасс ЛЧМ-зондирования в северо-восточном регионе России.</p>

    <p>The paper presents a method of interpreting data on oblique ionosphere sounding (OS) with a continuous chirp signal. Hybrid algorithms for automatic interpretation of ionograms by selected points with significant amplitude obtained during secondary data processing for various heliogeophysical conditions have been developed and implemented. For the conditions of the two-layer ionosphere, an interpretation method has been worked out which involves analyzing histograms for the distribution of points with significant amplitude, which fall into a model mask constructed from the results of modeling of the distance-frequency characteristic for propagation when it moves over the ionogram. For the multilayer ionosphere, the interpretation is based on the study of the ionogram amplitude relief. The algorithms for extracting tracks of signals reflected from sporadic layers are examined separately. We report the results of interpretation of ionograms obtained on the network of chirp sounding radio paths in the northeastern region of Russia.</p>
