The widespread using of methods of spatial-temporal processing causes new approaches for increasing of accuracy. At this work we consider moving radio sources and we also offer algorithms for adaptive control of radiation pattern. We offer use circular antenna systems in order to improve the efficiency of spatial-temporal processing. It helps to exactly determine the direction to radio source and to create asymetric radiation pattern. We proved our maths algorithms of tuning the vector of weights for adaptive antennas. Algorithms provide correction of vector to decrease errors, that are caused by changes of direction to radio source. We also offer the solution for the problem when perfomance of adaptive system depends on prolonged stationary intervals and nonstationary short-term time intervals. Results are offered for three different examples of signal clutter: the position of the source and the receiver does not change (stationary); when the position of source changes; when the signal clutter is nonstationary.
