In the present work synthesized algorithm collective compensation nonstationary distortions of optical radiation, caused by its propagation in a turbulent atmosphere, and measurement of angular coordinates of the source of this radiation. The definition of angular coordinates is carried out on the basis of the maximum likelihood method, which ensures minimization of the standard deviation of the estimates from the true bearing from a mobile object. Synthesized algorithm intended to be implemented in an adaptive optical systems, phase conjugation. The size of the sensor phase front significantly affect the accuracy of estimates of the angular coordinates. Most strongly this effect in the case of weak turbulence. This is because in the case of weak turbulence to the size of the sensor more sensitive precision recovery phase front, which, in turn, part-precision measurement of angular coordinates.
