Abstract:
Modern navigation receivers global satellite systems have a significant drawback - low interference immunity [1−7]. To solve this problem, radio interference suppressed navigation receivers are based on phased array antennas using adaptive beamforming tech-niques. Pattern control is widely used in applications such as navigation, radar, wireless communication and others. Currently, the most popular methods of digital typed beamforming. Their main advantage is the possibility of formation of special types of the antenna system navigation receiver - lows (failures) in the appropriate direction to the source of interference and highs in the direction of the useful signal. Due to this compensated (suppressed) interference and the useful signal is accumulated from directions other than the interference. The overall effect of this treatment is determined by the level of use and completeness of the differences, as well as taking into account the quality of each of them, depending on the degree of knowledge the statistical characteristics of the signals and interference.
