The study about the direction-of-arrival (DOA) estimation for wideband signals is a basic topic of Signal Processing. The method called test of orthogonality of projected subspaces (TOPS) does not require initial values to form focusing matrix compared with the coherent signal subspace method (CSSM)
but it has poor performance for coherent wideband signals at low signal-to-noise ratio (SNR). Based on the lack of the conventional TOPS
this paper reconstructs a set of new matrices with the narrowband correlated matrices coming from the DFT decomposition of the array output and modifies the method frame of the conventional TOPS. So we get a set of reconstructed matrices with full rank corresponding to each frequency bin
and which have no array aperture loss. The improved TOPS can estimate the DOA for coherent wideband sources at low SNR
and enhances the performance of the conventional TOPS. Simulation results show that the improved TOPS is effective
and the total performance of which is similar to the rotational signal-subspace (RSS) method. (2012) Trans Tech Publications.
