METHOD FOR DETERMINING TRANSPARENCY OF INHOMOGENEOUS ATMOSPHERE Russian patent published in 2018 - IPC G01S17/95 G01W1/02 

FIELD: measuring equipment.

SUBSTANCE: method for determining the transparency of an inhomogeneous atmosphere involves sending light pulses from points spaced in space into the atmosphere along intersecting sensing paths passing along three noncollinear directions, with formation of segments between the points of their intersection of two probing regions having a common scattering volume. Reception of echoed signals at the sending points is performed. Echoed signals on segments forming regions are accumulated, and the characteristics of the atmosphere are determined by the echoes signals received from the intersection points of the traces and accumulated. Reduction of both sensing areas is executed and the procedure is repeated to a given level of coincidence of two successive results of determining the characteristics of the atmosphere, by which its transparency is found.

EFFECT: technical result consists in accuracy increase of determining the characteristics of the atmosphere by reducing the degree of approximation of the solution with size reduction of the sounding areas and reducing the random error in the measurement process.
