This thesis presents an analysis of the performance of an air-to-air optical communication link in the presence of atmospheric turbulence. As aircraft travel through the atmosphere, they encounter regions of atmospheric turbulence. While harmless to radio frequency communications, these regions of turbulence can cause both intensity and phase fluctuations within an optical beam. as a result, the communication link bit error rate rises. To evaluate the performance of such a link, a computer simulation was developed. By varying such parameters as the speed fo the aircraft, its altitude, and propagation path length, a determination could be made about link performance. The results obtained from the simulation showed that atmospheric turbulence plays a significant role in determining link performance. Originator-Supplied keywords include: Optical Communications, Laser Communications, and Turbulence.

In the last several years considerable progress has been made toward the development of adaptive systems which can compensate for the deleterious effect of atmospheric turbulence on air/air and air/ground optical communications links. One promising method is reciprocity tracking in which a beacon located on the receiver is used in real time to adjust the wavefront of the transmitter. A beacon signal is emitted at x and the phase distribution of this signal is sensed in the plane x = 0. The phase of the transmitter field is then continuously adjusted so that it is the negative of the received beacon phase distribution. because of atmospheric reciprocity, this then continuously compensates for the phase fluctuations induced on the transmitted field by the turbulent medium between the transmitter and receiver.
