Сделан акцент на особенностях программной реализации алгоритма. Описаны особенности параллельных вычислений функции на процессорах игровых видеокарт. Определено время, затрачиваемое на параллельные вычисления 16 частотно-временны́х функций в многоканальной РЛС. </p></abstract><trans-abstract xml:lang="en"><p>The paper describes the algorithm of fast calculation of the amplitude-range-Doppler surface. The features of the software implementation of the algorithm are drawn. The nuances of parallel computing of the surface on graphics processing units of the gaming graphics card are shown. The result, the sixteen surfaces parallel computing time for multi-channel radar, is presented. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Радиолокация</kwd><kwd>цифровая обработка</kwd><kwd>функция неопределенности</kwd><kwd>корреляционная функция</kwd><kwd>доплеровское смещение частоты</kwd><kwd>задержка</kwd><kwd>быстрое преобразование Фурье</kwd><kwd>графический процессор</kwd><kwd>параллельные вычисления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Radar</kwd><kwd>digital processing</kwd><kwd>ambiguity function</kwd><kwd>cross-correlation</kwd><kwd>Doppler shift</kwd><kwd>delay</kwd><kwd>fast Fourier transformation</kwd><kwd>graphics processing units</kwd><kwd>parallel computing</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">Bistatic radar: emerging technology / ed. by M.
