Актуальность разработки обусловлена наличием проблемы несанкционированного доступа на закрытые объекты, а также объекты энергетического сектора, такие как газо/нефтепроводы. Наибольшую опасность в плане незаметного проникновения на охраняемую территорию в последнее время представляют собой беспилотные летательные аппараты, позволяющие не только проводить качественную фото- и видеосъёмку, но и осуществлять перенос грузов, представляющих потенциальную угрозу безопасности объекта. Разработанная РЛС осуществляет всепогодное и круглосуточное обнаружение малоразмерных подвижных целей. Использование технологии фазового метода измерения угловых координат позволило отказаться от движущихся частей конструкции, значительно повысив её надёжность, а также увеличить интервалы обслуживания. Применение широкополосных сложных сигналов с большой базой (квазинепрерывный режим работы) обеспечивает повышенную помехоустойчивость, скрытность и дальность обнаружения.</p></abstract><trans-abstract xml:lang="en"><p>The article describes technical realization of a compact S/C-band radar for the site protectrion. Nowadays, closed facilities, factories, and energy sector facilities, such as gas / oil pipelines are facing the problem of unauthorized access. The greatest danger in terms of untracked trespassing the border of the protected area in recent years are unmanned aerial vehicles (UAVs). Such UAVs allow not only to carry out high-quality photo / video, but also to carry cargo that pose a potential threat to the security of the object. The developed radar system provides all-weather and round-the-clock detection of small mobile targets. The use of the technology of the phase method of measuring the angular coordinates allowed us to remove the moving parts of the radar, significantly increasing its reliability, as well as to increase the service intervals. The use of wideband signals with a large base (quasi-continuous mode) provides increased noise immunity, secrecy and detection range.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиолокация</kwd><kwd>сложные сигналы</kwd><kwd>беспилотные летательные аппараты (БпЛА)</kwd><kwd>квазинепрерывные сигналы (КНС)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radar</kwd><kwd>SAR</kwd><kwd>wideband signals</kwd><kwd>unmanned aerial vehicle (UAV)</kwd><kwd>quasicontinuous signals (QCS)</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">IAI ELTA Systems Ltd.
