Abstract

Способ определения прозрачности атмосферы, при котором осуществляют посылку в атмосферу световых импульсов из точек, разнесенных в пространстве, по пересекающимся трассам зондирования, проходящим не менее чем по трем неколлинеарным направлениям; с образованием области зондирования отрезками между точками их пересечения, осуществляют прием эхо сигналов в точках посылки, а прозрачность атмосферы определяют по мощностям этих сигналов с использованием расчетных формул, отличающийся тем, что осуществляют посылку в атмосферу световых импульсов по дополнительным трассам с образованием дополнительной области зондирования, имеющей общий рассеивающий объем с первой областью, накапливают эхо сигналы на отрезках, образующих области, определяют характеристики атмосферы по эхо сигналам, принятым из точек пересечения трасс и накопленным, уменьшают обе области зондирования и повторяют процедуру до задаваемого уровня совпадения двух последовательно полученных результатов определения характеристик атмосферы, по которым находят ее прозрачность. A method for determining the transparency of the atmosphere, in which light pulses are sent to the atmosphere from points spaced in space along intersecting sounding paths passing in at least three noncollinear directions; with the formation of the sounding region by segments between the points of their intersection, echo signals are received at the sending points, and the transparency of the atmosphere is determined by the power of these signals using calculation formulas, characterized in that they send light pulses into the atmosphere along additional paths with the formation of an additional sounding region, having a common scattering volume with the first region, echo signals are accumulated on the segments forming the regions, atmospheric characteristics are determined from the echo signals , taken from the intersection points of the paths and accumulated, reduce both sensing areas and repeat the procedure to the specified level of coincidence of two successively obtained results of determining the atmospheric characteristics by which its transparency is found.
