Использована модель наиболее адекватной негауссовской радиолокационной помехи от взволнованной морской поверхности, огибающая которой описывается К-распределением плотности вероятности. В модели помех учитывается внутренний гауссовский шум приемника. Для различных значений параметров модели помехи получены амплитудные характеристики нелинейного элемента и зависимости коэффициента подавления от отношения "помеха/шум". </p></abstract><trans-abstract xml:lang="en"><p>The method of non-linear amplitude suppression of radar clutter from a sea surface in the coherent band path of the receiver is considered. The model of the most adequate nongaussian radar clutter from the rough sea surface which envelope is based on K-distribution of density of probability is used. The mathematical model of clutter is considered. For various values of parameters of model of clutter amplitude characteristics of a non-linear element and dependence of coefficient of suppression on the relation a clutter/noise are under construction. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Морские помехи</kwd><kwd>нелинейная фильтрация</kwd><kwd>К-распределение</kwd><kwd>гауссовские помехи</kwd><kwd>негауссовские помехи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Sea clutter</kwd><kwd>non-linear filtering</kwd><kwd>K-distribution</kwd><kwd>Gaussian clutter</kwd><kwd>nongaussian clutter</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">Ward K., Tough R., Watts S.
