| Abstract(in English) | The gain/phase errors of the antenna array and mutual coupling among elements cause array manifold errors in MUSIC spectrum. The authors proposed parametric calibration technique which utilizes orthogonal property between signal and noise subspace. The method can estimate gain/phase error and mutual coupling matrices directly. This type of the method is required when we use the root-MUSIC, the MODE, the ESPRIT in some array configurations, and also the Spectral-MUSIC for coherent signal detection with spatial smoothing preprocessing. On the other hand, calibration technique which utilizes measured array manifold is one of the well known method for the Spectral-MUSIC algorithm. In this report, we verify performance of above two types of calibration technique. Experimental results show that good calibration performance can be also obtained by the parametric method. |
