В качестве источника зондирующего излучения в ПЛД-1 используется в твердотельный импульсный лазер на АИГ:Nd с диодной накачкой. Приведены особенности конструкции и основные технические характеристики лидара. Представлены некоторые результаты первых натурных экспериментов, выполненных в прибрежных водах Черного моря. В ходе этих экспериментов были уверенно зарегистрированы эхосигналы от плоской и сферической мишеней при протяженности подводного участка трассы зондирования более чем в двое превышающим глубину видимости белого диска Zб. Продемонстрировано преимущество поляризационного метода локации погруженных объектов с регистрацией кроссполяризованной компоненты эхо-сигнала.</p></abstract><trans-abstract xml:lang="en"><p>A new marine polarization lidar PLD-1 was developed. It was designed for determine the spatial structure of the fields of hydrooptical characteristics, as well as recording and determining the position of objects in the seawater column. A solid-state pulsed YAG: Nd laser with diode pumping is used as a source of sounding radiation. The design features and the main technical characteristics of the lidar are given in the paper. Some results of the first full-scale experiments performed in the coastal waters of the Black Sea are presented. During these experiments, echo-signals from the flat and spherical targets were confidently recorded with the length of the underwater portion of the sounding path more than two times longer than the depth of visibility of the Secchi disk Zb. The advantage of the polarization method for locating immersed objects with registration of the cross-polarized component of the echo-signal is demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>морской поляризационный лидар</kwd><kwd>дистанционное зондирование</kwd><kwd>оптические неоднородности</kwd><kwd>локация мишеней</kwd></kwd-group><kwd-group xml:lang="en"><kwd>marine polarization lidar</kwd><kwd>remote sensing</kwd><kwd>hydro-optical in homogeneities</kwd><kwd>target location</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">Vasilkov A.
