Abstract
A statistical analysis of the spatial-temporal DFT projection technique for estimation of the direction-of-arrivals (DOAs) of wideband signals is presented. One of the advantages of this technique is its simple implementation as it does not require the construction of focusing matrices. Simulation results and comparisons with existing techniques show satisfactory performance, especially at low signal-to-noise (SNR) ratios and a relatively low SNR threshold
