Аннотация: Hybrid-reflector multibeam antennas employed in satellite navigation systems transform adopted accelerated spatial filtering algorithms. In order to accelerate the algorithm, the adaptive system selects an amplitude-phase distribution from a set of precalculated distributions for various interference signaling environments in the bПоказать полностьюeam where the interference signal affects the radiation pattern of the main lobe. Specification of the weighted coefficients is performed after the most appropriate amplitude-phase distribution has been selected. Data from the weighted coefficients calculations is used for null formation in radiation patterns of beams where interference affects the side lobes.
