Основой интеллектуальных систем помощи водителю зачастую являются радары, осуществляющие обнаружение, разрешение, сопровождение различных классов целей. Применение распределенной системы, основанной на MIMO-технологии, позволяет в значительной степени улучшить характеристики разрешения объектов по углу. При этом возникает сложность в обеспечении когерентного режима обработки данных, поступающих с двух или более радаров. Данная статья посвящена описанию радиолокационной системы миллиметрового диапазона длин волн с улучшенной разрешающей способностью по угловой координате в сравнении с моностатической и вопросу обеспечения синхронизации радаров, входящих в исследуемую систему.</p></sec><sec><title>Цель работы</title><p>Цель работы. Повышение разрешающей способности по угловой координате распределенной радиолокационной системы при совместной когерентной обработке сигналов двух MIMO-радаров.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование разрешающей способности системы, состоящей из двух разнесенных радаров, проводилось экспериментально с использованием полнофункционального макета, для которого были разработаны алгоритмы фазовой синхронизации и совместной цифровой обработки сигналов, а также соответствующее программное обеспечение.</p></sec><sec><title>Результаты</title><p>Результаты. Применение общего внешнего источника опорного сигнала в MIMO-радарах позволяет реализовать когерентный режим работы системы. Использование двух MIMO-радаров обеспечивает формирование бистатической виртуальной антенной решетки, что в 2 раза улучшает разрешающую способность по углу в сравнении с радаром, число приемных каналов которого в 2 раза меньше, чем размер бистатической виртуальной решетки.</p></sec><sec><title>Заключение</title><p>Заключение. Экспериментальные исследования показывают увеличение разрешающей способности по угловой координате при формировании бистатической виртуальной антенной решетки. Использование внешнего опорного генератора позволяет обеспечить когерентный режим работы двух радаров и достигнуть точности взаимной синхронизации фаз в каналах бистатических подрешеток в несколько градусов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Intelligent driver assistance systems are increasingly employing radar systems to detect, resolve, and track various classes of targets. The use of MIMO-based distributed systems allow the characteristics of object resolution by angle to be significantly improved. However, this is associated with the difficulty to ensure a coherent mode of processing data entering from two or more radar systems. This work compares a millimeter wavelength range radar system with improved angular resolution with a monostatic system. The issue of ensuring synchronization of radars comprising the system under study is addressed.</p></sec><sec><title>Aim</title><p>Aim. To increase the angular resolution of a distributed radar system with tandem coherent signal processing of two MIMO radars.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The resolution of a system consisting of two spaced radars was investigated experimentally using a fully functional layout. Algorithms for phase synchronization and collaborative digital signal processing, along with appropriate software, were developed.</p></sec><sec><title>Results</title><p>Results. The use of a common external reference signal source in MIMO radars makes it possible to implement a coherent system operation mode. Placement of two spaced MIMO radars ensures the formation of a bistatic virtual antenna array, which doubles the angle resolution, compared with a radar whose number of receiving channels is two times smaller than the size of a bistatic virtual array.</p></sec><sec><title>Conclusion</title><p>Conclusion. The conducted experimental studies demonstrated an increase in angular coordinate resolution during the formation of a bistatic virtual antenna array. The use of an external reference generator ensures the coherent operation of two radars, improving the accuracy of mutual phase synchronization in the channels of bistatic subarrays by several degrees.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бистатическая виртуальная решетка</kwd><kwd>MIMO-радар</kwd><kwd>разрешающая способность по угловой координате</kwd><kwd>когерентная обработка сигналов</kwd><kwd>диаграмма направленности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bistatic virtual array</kwd><kwd>MIMO radar</kwd><kwd>angular coordinate resolution</kwd><kwd>coherent signal processing</kwd><kwd>radiation pattern</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 RADAR / H.
