Abstract
Лазерный дистанционный способ оценки мгновенной скорости и направления ветра, состоящий в том, что атмосферу облучают двумя зондирующими лазерными пучками, регистрируют реализации сигналов обратнорассеянного излучения от атмосферы этих двух лазерных пучков и определяют поперечную и продольную составляющие скорости ветра, используя пространственную и временную корреляционную обработку регистрируемых сигналов, отличающийся тем, что атмосферу облучают одним зондирующим лазерным пучком, регистрируют в течение времени измерения пространственные реализации сигналов обратнорассеянного излучения от атмосферы одного лазерного пучка в зависимости от расстояния от лидара, выделяют на двумерной плоскости «время измерения - расстояние от лидара» произвольно выбранную неоднородность сигнала обратного рассеяния и определяют поперечную и продольную составляющие мгновенной скорости ветра, используя анализ размеров неоднородности обратнорассеянного излучения в двумерной плоскости «время измерения - расстояние от лидара».A remote laser method for estimating the instantaneous wind speed and direction, consisting in the fact that the atmosphere is irradiated with two probing laser beams, the implementation of backscattered radiation signals from the atmosphere of these two laser beams is recorded, and the transverse and longitudinal components of the wind speed are determined using spatial and temporal correlation processing of the recorded signals , characterized in that the atmosphere is irradiated with a single probe laser beam, recorded during the measurement time The random realizations of backscattered radiation signals from the atmosphere of one laser beam depending on the distance from the lidar, select an arbitrary chosen inhomogeneity of the backscattering signal on the two-dimensional plane "measurement time - distance from lidar" and determine the transverse and longitudinal components of the instantaneous wind speed using analysis of the dimensions of the inhomogeneity of the backscattered radiation in the two-dimensional plane "measurement time - distance from the lidar."
