Abstract

Expressions are determined for the relationship between the crosswind speed and the temporal-frequency spectra of the log-amplitude fluctuations of plane and spherical waves propagating over folded paths in a turbulent atmosphere. The results of the spherical wave indicate that in addition to information about turbulent motion, the spectral content contains a path position modulation that depends on the detector displacement from the center of the wave. This displacement may lead to errors in the determination of turbulent motion from optical measurements.
