Annotations languages:

Angle-of-arrival measurement using radio technical systems with multibeam antenna is considered in the paper. Possibilities of increasing the effectiveness of multichannel direction finding in the system with multi-frequency multi-beam scan at the expense of diminishing the influence of signal intensities in receiving channels and using the surplus information from additional measurers of antenna receiving modules with wide beams are analyzed. The effectiveness of method is confirmed by the results of analytical calculation and mathematical simulation.
Keywords: antenna pattern, multifrequency and multibeam antenna array, angle-of-arrival
