摘要
The publication presents a method for interference and noise reduction in antenna arrays systems, mainly applicable in radio communication, microwave systems, radars, where there arc at least two signal paths and there is a need to reduce interference with different phases or amplitudes. The research used the method described in Polish patent PL-226101 "Method of noise and noise reduction in systems with two signal paths and phase filter" and obtained positive results. This invention relates to a simple and very effective method of eliminating noises and interferences, mainly in diversity receiving systems (antenna arrays), where eliminates all pairs of signals with different phases or different amplitudes and passes only signals with similar phases and amplitudes. The solution allows to strongly increase directional of antenna arrays and reduce the noise significantly and thereby maximize the signal-to-noise ratio (S/N).
