Probability of False Peaks Circular and Concentric Array Antennas Direction

Evaluation of angular coordinates of radio sources has attracted a great interest in areas such as radar, sonar and wireless telecommunications systems. The problem of estimate the radar angular coordinates of radio sources is the key to improve productivity,. however, in the wireless telecommunications systems information, the coordinates are enables the spatial separation to increase operating members in this paper, the functioning of the radio direction-finding techniques in the system ring and concentric array antennas is investigated. we focus on the issue of false peaks in the DF relief ring and concentric array antennas. A radio direction-finding method MUSIC with super resolution are considered and discussed.
