This report is the final technical report on work performed on Contract F30602-77-C-0099, and covers all work done under this contract. This report presents analysis, a set of computer simulation programs, and a set of simulation results that demonstrate that an adaptive compensation pointing and tracking servo loop can be closed in a long range space engagement that permits high servo bandwidth tracking performance with point-ahead and boresight error compensation that adapts to insure that the laser spot is held on the desired aimpoint. A laser spot position technique based on exploitation of speckle statistics is developed that allows the true laser spot position to be sensed and compensated for whether or not a glint point even a strong glint point is present. Simulation results demonstrate the performance at the concept and lead to the conclusion that the technique should be applicable with extension, to higher order adaptive optics control problems - thus providing high servo bandwidth performance together with compensation for any bias errors.
