REMOTE PROBING OF OPTICAL STRENGTH OF ATMOSPHERIC TURBULENCE AND OF WIND VELOCITY

A procedure for determining the optical strength of turbulence of the atmosphere and the wind velocity at various attitudes by measuring the spatial and temporal covariance of scintillation is developed. Emphasis is placed on the development of the formal relationships that have to be inverted to obtain the desired results. For determination of optical strength of turbulence, it is a linear integral equation that is developed. However, for determination of remote wind velocity, a nonlinear integral equation is obtained. A computer approach for solving each of the equations is suggested. The configuration and performance requirements of the measurement apparatus are discussed.
