Abstract
In this paper, the Capon beamformer and the MUSIC algorithm are used to estimate the direction of the single narrowband interference in the Beidou B3 band. Results show that the angle dimension can be estimated depends on the antenna formation. Array error was also corrected by the way of calibration method under unideal condition. The mutual coupling matrix and the amplitude-phase difference matrix were extracted by HFSS, and their inverse matrix were substituted into the algorithm to correct the results. Computer simulation experiments prove this method is effective.
