Abstract
The purpose of this paper is the DOA estimation of the wideband sources using an array of sensors. A fast subspace based method without eigendecomposition of the spectral matrix of the sensor array improved in the presence of the noise and extended to the wideband signals. New and fast transformation matrices are developed to construct the coherent signal subspace in the presence of the uncorrelated noises along the antenna with different powers. As an illustration, simulation results are exhibited to show the performance of this method
