Abstract

Subband-based eigenstructure method for bearing estimation (Xue, Wang and Liu (2004), Xue and Wang (2004)) require a mapping back manipulation after the subband frequency is estimated. In this paper, we propose a non-mapping back method to estimate the fullband bearings in the subband domain. The proposed method enhances the signal energy and reduces the root mean square error (RMSE). Simulations results show the decorrelation capability of coherent sources with appropriate subband division.
