Phase Difference and Angle-of-Arrival Fluctuations in Tracking a Moving Point Source.
The correlation function and power spectrum of phase difference fluctuations and angle-of-arrival fluctuations are calculated for tracking a moving spherical wave optical source through atmospheric turbulence. For Kolmogorov turbulence, it is shown that, in order to freeze effectively the received wavefront, the scanning frequency must be essentially equal to the highest frequency contained in the power spectrum.
