Annotations languages:

Procedure of measuring and indemnification of distortions of phase front of radio wave which spreads in nonhomogeneous environment is considered in the article. A method and algorithm which is based on measuring the linear array of spatial spectrum of these distortions the method of Newton is offered. Measuring is carried out in the tracker mode. The criterion of quality is choose achievement of signal power in the summator of linear fhased fntenna arrays of maximal value. It is rotined that exactness of measuring of fluctuations of phase in a radio wave depends on a relation signal / noise is in all of linear fhased fntenna arrays, and the process of adaptation at small errors can be completed for one iteration.
Keywords: distortion of phase front an environment, adaptation
