В современных системах помощи водителю важную роль играют радары миллиметрового диапазона (mmWave). Однако в условиях городской застройки эффективность традиционных методов оценки направления прихода сигнала (DOA) снижается из-за эффектов многолучевого распространения, порождающих ложные цели. В статье рассматривается метод распознавания сигналов, вызванных однократным отражением и многолучевым распространением, и оценки их направления прихода.Цель работы. Разработка и экспериментальное исследование комплексного подхода к оценке угловых координат объектов в MIMO-радарах при наличии многолучевого распространения.Материалы и методы. Реализован двухэтапный конвейер обработки сигналов. На первом этапе выполняется предварительная классификация типа радиолокационного сценария (прямая видимость, многолучевое распространение, множественная цель) с использованием сверточной нейронной сети. На втором этапе осуществляется оценка направления прихода сигнала с помощью стандартного метода MUSIC и метода MUSIC с реконструкцией корреляционной матрицы сигнала. Обучение и проверка выполнялись на гибридном наборе данных, состоящем из данных, сформированных с помощью модели распространения сигнала, и реальных измерений с MIMO-радара TI AWR1843.Результаты. Предложенный подход позволяет с высокой точностью разрешать сценарии распространения сигнала и оценивать угловые координаты. Исследования проводились на открытом датасете. Показано, что результат классификации согласуется с математической моделью распространения сигнала.Заключение. Результаты подтверждают эффективность применения предложенного подхода для обнаружения многолучевого распространения, что позволяет повысить надежность оценки сцены MIMO-радаром.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Today, millimeter-wave radars are a key component of driver-assistance systems. However, in urban scenarios, the performance of conventional methods for estimating the direction of arrival of signals (DOA) is degraded by multipath effects, which can lead to ghost targets. This article describes an algorithm for classifying signals caused by single reflection and multipath propagation and estimating their DOA.Aim. To develop and investigate experimentally a method for estimating the angular coordinates of objects in MIMO radars in the presence of multipath propagation.Materials and methods. A two-stage signal processing algorithm was proposed. In the first stage, a convolutional neural network classifies the signal scenario as one of the following types: direct path, multipath, or multiple target. In the second stage, the direction of arrival is estimated by the standard MUSIC method and a modified MUSIC method based on reconstruction of the signal correlation matrix. Training and validation were performed on a hybrid dataset consisting of data generated using a signal propagation model and actual measurements obtained by a TI AWR1843 MIMO radar.Results. The proposed algorithm can be used to classify signal propagation scenarios with high accuracy and to estimate the angular coordinates of objects. The proposed method was tested on an open dataset. The results show that the classification results are consistent with the mathematical model of signal propagation.Conclusion. The proposed approach is effective for multipath detection. The proposed algorithm allows the robustness of MIMO radar scene estimation to be improved.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>MIMO-радар</kwd><kwd>физическая и виртуальная антенная решетка</kwd><kwd>многолучевое распространение</kwd><kwd>оценка направления прихода</kwd><kwd>корреляционная матрица</kwd></kwd-group><kwd-group xml:lang="en"><kwd>MIMO radar</kwd><kwd>physical and virtual antenna array</kwd><kwd>multipath propagation</kwd><kwd>direction of arrival</kwd><kwd>correlation matrix</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Automotive radars: A review of signal processing techniques / S.
