This paper deals with the problem of using radio systems optimal spatial structures for receiving field sensors, having characteristics of spatial reconfiguration. This basic function is assigned to adaptive antenna arrays, affecting the efficiency of signal processing in radio systems. The current task is convergence increasing rate of an adaptive adjustment process for weight coefficients vector in antenna array with variable spatial structure and increasing the efficiency of spatially concentrated interferences rejection. Also, it is shown, that pre-processing with adjustment of adaptive antenna array elements gives an opportunity to prevent a divergence of adaptive adjustment process at rate increasing, and to improve rate of system in conditions of adaptation time limitation.
