Рассмотрена техническая реализация тракта формирования и обработки сверхширокополосных квазинепрерывных ЛЧМ-сигналов. Обсуждаются вопросы применения адаптивного спектрального анализа сигналов с использованием метода их «сверхразрешения».</p></abstract><trans-abstract xml:lang="en"><p>The results of designee and research of ground penetration radar, using ultra wide band signals with line frequency modulation are investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>линейная частотная модуляция (ЛЧМ)</kwd><kwd>ЛЧМ-радиолокатор</kwd><kwd>подповерхностное зондирование</kwd><kwd>формирование и обработка сверхширокополосных сигналов</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">Радиоэлектронные системы: основы построения и теория.
