Abstract

Способ определения уклонов водной поверхности, заключающийся в том, что заданную точку водной поверхности зондируют неподвижным вертикальным лучом лидара, расположенного на расстоянии Н от водной поверхности, регистрируют блики зеркального отражения и по ним рассчитывают плотность вероятностей компоненты уклонов водной поверхности, по которой определяют статистические моменты уклонов, отличающийся тем, что определяют или одну, или две компоненты уклонов водной поверхности, при определении каждой из компонент одновременно с зондированием вертикальным лучом заданную точку водной поверхности зондируют при ненулевых углах падения неподвижными лучами двух или более лидаров, каждый из которых расположен на расстоянии Н от заданной точки водной поверхности и лучи которых лежат в одной плоскости с вертикальным лучом, регистрируют всеми лидарами блики зеркального отражения и рассчитывают плотность вероятностей соответственно или одной, или двух компонент уклонов водной поверхности, при этом при определении двух компонент плоскости расположения лучей лидаров, предназначенных для определения каждой из компонент, взаимно перпендикулярны.A method for determining water surface slopes, namely, that a given point of the water surface is probed by a fixed vertical beam of a lidar located at a distance H from the water surface, specular reflections are recorded and the probability density of the components of the slopes of the water surface is calculated from them, according to which the statistical moments of the slopes are determined characterized in that either one or two components of the slopes of the water surface are determined when each of the components is determined simultaneously with the probe By a vertical beam, a given point of the water surface is probed for non-zero angles of incidence by the fixed rays of two or more lidars, each of which is located at a distance H from a given point of the water surface and whose rays lie in the same plane with the vertical beam, the specular reflection is recorded by all lidars and calculated the probability density, respectively, of either one or two components of the slopes of the water surface, while determining two components of the plane of the arrangement of the rays of lidars, Achen to determine each of the components are mutually perpendicular.
