MUSIC algorithm that is used for DOA estimation, uses DFT (FFT) for its computation and calculation.

This could help

Direction arrival estimation is nothing but estimation spatial frequencies from the spatial samples generated by antenna arrays.It stuck with finite resolution ( limited by number of Antennas), Where as MUSIC is one such algorithm which increases the resolution of spatial frequencies compared to FFT based one

Mohan Bansal

Extracting the narrowband component form the wideband signal u can get the high resolution of the direction of arrival (DOA) in the frequency domain with the help of MUSIC algorithm.

U can get more information by this file.
