В ней представлена структурная схема разработанного прототипа радиолокационной системы и дано описание структурных схем основных функциональных блоков: блока формирования и обработки сигналов, блока обработки координат, блока формирования радиолокационного изображения. Дана оценка требуемых для реализации обработки сигналов ресурсов программируемой логической интегральной микросхемы. В конце статьи приведены примеры радиолокационных изображений, полученных в ходе натурных испытаний прототипа РЛС. Новизна разработки обуславливается применением шумоподобных квазинепрерывных сигналов и возможностью получения радиолокационного изображения земной поверхности в режиме реального времени. Использование квазинепрерывных сигналов позволяет повысить скрытность и помехоустойчивость системы, а также снизить пиковую мощность передатчика. Данные особенности являются необходимыми для размещения радиолокационной системы с РСА на малогабаритных беспилотных летательных аппаратах.</p></abstract><trans-abstract xml:lang="en"><p>The article describes technical realization of compact UAV based X/L-band SAR. It presents a block diagram of the developed radar prototype and describes the structural diagrams of the main functional blocks: the signal generation and processing unit, the coordinate processing unit, the radar image generation unit. The estimation of the resources required for the implementation of signal processing of a programmable logic integrated circuit (FPGA) is given. Examples of radar images obtained during full-scale tests of the radar prototype are given at the end of the article. Novelty of design based on two main factors: broadband quasi-continuous signals (QCS) and the real-time land surface imaging. The usage of QCS leads to the higher stealthiness and noise-immunity. The peak power of transmitter is decreased also. This features are highly demanded while designing RSA systems that can be used on compact UAV.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиолокация</kwd><kwd>РСА</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>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.
