   <abstract xml:lang="ru">
    <p>Приведена схема моделирования характеристик КВ-радиосигналов на трассах различной протяженности на основе волноводного подхода — метода нормальных волн. Используется представление поля регистрируемого сигнала в виде ряда произведений функций Грина углового оператора, коэффициентов возбуждения и коэффициентов приема отдельных нормальных волн. Разработаны алгоритмы расчета дистанционно-частотных, частотно-угловых и амплитудных характеристик сигналов в больших пространственных областях на основе анализа и численного суммирования ряда нормальных волн. Реализован комплексный алгоритм моделирования условий распространения КВ-радиосигналов, включающий модель среды, алгоритмы расчета характеристик сигналов и оперативную диагностику радиоканала. Проведено сопоставление результатов моделирования характеристик распространения КВ-сигналов и экспериментальных данных наклонного зондирования на трассах различной протяженности и ориентации. Для анализа экспериментальных ионограмм, определения максимальных применимых частот различных мод распространения на радиотрассах используется методика автоматической обработки и интерпретации ионограмм наклонного зондирования.</p>

    <p>We present a scheme for modeling HF radio signal characteristics along paths of different lengths, which is based on the waveguide approach — the normal mode method. We use a representation of the recorded signal field in the form of Green function products of the angular operator, excitation coefficients, and reception coefficients of individual normal modes. Algorithms have been developed for calculating distance-frequency, frequency-angular, and amplitude characteristics of signals in large spatial regions through analysis and numerical summation of normal mode series. We have implemented a complex algorithm for simulating propagation conditions of HF radio signals, which includes a medium model, algorithms for calculating signal characteristics, and operational diagnostics of radio channel. We have compared the results of the HF signal propagation characteristic modeling and the experimental oblique sounding data obtained along paths of different lengths and orientation. To analyze experimental ionograms, determine the maximum usable frequencies for propagation modes along radio paths, we employ the method of automatic processing and interpretation of oblique sounding ionograms.</p>
