Установлено отсутствие влияния доплеровского сдвига эхосигнала на нарастающий фронт профиля. Показано, что задний фронт профиля при зондировании импульсом с линейной частотной модуляцией также нечувствителен к доплеровскому смещению, тогда как при зондировании фазомодулированным импульсом длительность профиля при учете доплеровского рассеяния существенно сокращается.</p></abstract><trans-abstract xml:lang="en"><p>In the analytical approximation of time dependent average power of a satellite altimeter echo-signal (power profile) the Doppler scattering of individual specular point responses is usually neglected. Meanwhile, in the modern Ka-band altimeters the Doppler shift of reflection from a point near illuminated spot edge is greater than the frequency resolution. The equation for the power profile allowing for the Doppler effect is derived. While, as expected, the profile leading edge is not influenced by the Doppler shift, there is critical discrepancy in the trailing edge behavior between ranging LFM and BPSK signals. If for the former the Doppler shift involvement does not change trailing edge steepness for the latter it makes the profile decrease much faster. Finally, the possibility to utilize the Doppler scattering to improve along-track altimeter resolution is discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Спутниковый высотомер</kwd><kwd>эхосигнал</kwd><kwd>доплеровское рассеяние</kwd><kwd>ЛЧМ-сигнал</kwd><kwd>ФМ-сигнал</kwd><kwd>синтезированная антенна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Satellite Altimeter</kwd><kwd>Echo-Signal</kwd><kwd>Doppler Scattering</kwd><kwd>LFM-Signal</kwd><kwd>BPSK-Signal</kwd><kwd>Synthetic Aperture</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">Комплексный спутниковый мониторинг морей России / О.
