Abstract:

Some results of experimental investigation of a spatiotemporal structure of a spherical wave reflected from a plane mirror in the turbulent atmosphere are presented. A low—frequency shift in temporal spectra of strong intensity fluctuations depending on the relation between the fluctuational and average components of wind velocity in the direction perpendicular to the propagation path is found as the observation point is removed from the strictly backward direction. An inhomogeneity in spatial correlation of strong intensity fluctuations in the receiver plane is determined. Cross correlation functions for various ratios of fluctuational component to the average value of wind velocity in the direction perpendicular to the propagation path are analyzed.
