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.

Aiming at the defects of the DOA algorithms under uniform linear array (ULA) only can estimate 180 degree unfaintness angles  in this paper  the algorithms of one-dimensional and two-dimensional DOA estimation for UWB signals based on unitary circular array (UCA) are proposed. In order to estimate DS-UWB signals within 360 degree angles  the UCA-CSM-RB-MUSIC algorithm is proposed  which can estimate 360 degree unfaintness azimuth angles. 2010 IEEE.
