В полуактивных радиолокационных системах (ПАРЛС) обнаружение целей выполняется по отраженным сигналам, излученным сторонними передатчиками. Отсутствие собственного передатчика определяет основные преимущества ПАРЛС в сравнении с активными РЛС: более низкая стоимость, скрытность работы, отсутствие электромагнитного воздействия на другие радиотехнические устройства и окружающую среду. В зависимости от доступности и зоны действия передатчиков, характеристик используемых сигналов, а также областей возможного применения ПАРЛС в качестве источников подсвета сегодня используют передатчики различных телекоммуникационных систем, включая теле- и радиовещание, навигационные и системы мобильной связи. Появление новых стандартов телекоммуникационных систем открывает дополнительные перспективы для развития ПАРЛС. Так, внедрение пятого поколения мобильной связи стандарта 5G с более высокой пропускной способностью потенциально может повысить точностные характеристики обнаружения целей в ПАРЛС, работающей по сигналам передатчиков нового стандарта. Исследование возможностей использования сигналов передатчиков стандарта 5G в качестве радиолокационного подсвета является актуальной задачей.</p></sec><sec><title>Цель работы</title><p>Цель работы.

Passive radars perform target detection based on reflected signals emitted by third-party transmitters. The absence of its own transmitter determines the main advantages of passive radars compared to conventional active radars: lower cost, silent operation, no electromagnetic impact on other radio equipment and the environment. Third-party transmitters of different telecommunication systems are currently used as illuminators of opportunity in passive radars. The emergence of new telecommunication standards opens additional prospects for the development of passive radars. For instance, the deployment of the fifth generation of mobile communications standard 5G with a higher bandwidth can potentially improve the accuracy of target detection in passive radars. Investigating the possibility of using signals from 5G transmitters for radar targets illumination is a relevant research task.</p></sec><sec><title>Aim</title><p>Aim. To analyze the possibilities, limitations and prospects of using 5G signals as illuminators of opportunity in passive radar systems.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The methods of passive radar theory, communication theory, and comparative analysis were used. Evaluation of potential characteristics of target detection was carried out using computer statistical modelling in the MATLAB environment.</p></sec><sec><title>Results</title><p>Results. The peculiarities of 5G signals from the point of view of their application as illumination signals in passive radars are investigated. The potential target detection characteristics of a passive radar using 5G signals for target illumination are evaluated and compared with those of passive radars operating on signals from other transmitters. The 5G signal provides an improved range and velocity resolution than signals from other telecommunication systems.</p></sec><sec><title>Conclusion</title><p>Conclusion. The comparative analysis shows that 5G NR signal transmitters can be used as a promising source of illumination in passive radar systems over relatively small areas.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полуактивная радиолокация</kwd><kwd>пассивный когерентный радиолокатор</kwd><kwd>сеть 5G</kwd><kwd>источник подсвета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>passive radar</kwd><kwd>passive coherent radar</kwd><kwd>5G network</kwd><kwd>illumination signal</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">Пассивная когерентная радиолокация / А.
