Abstract :
Increase of radiosystem interference immunity is reached by application of its optimal spatial structure. In order to overcome algorithm implementation difficulties, connected with hypersensibility to deviations from suppositions of non-stationary signal parameters and interferences parameters, the regularized algorithm of calculation robust spatial structure is offered. The solution of extreme problem, which belongs to the class of ill-conditioned problems, is searched on basis of representation of spatial structure as element of metric space. The comparative analysis of system efficiency with optimal spatial structure in static and dynamic operating modes is carried out.
