Fast algorithm for the wideband array processing using a two-sided correlation transformation

The purpose of this paper is the passive angular location of the wideband sources using an array of sensors. The improvement of the two-sided correlation transformation (TCT) is proposed, only the signal subspace estimated at each frequency is transformed by focusing matrices such that to obtain the coherent signal sub-space for all the analysis band. The simulation results show that the proposed algorithm reduce the computational load compared to the original version TCT.
