Root-MUSIC-based joint TOA and DOA estimation in IR-UWB

Tongxin xuebao, 2014
The parameters can be estimated via two-dimensional (2D) multiple signal classification (MUSIC) algorithm, in which the two-dimensional spectral peak searching, however, requires much higher computational complexity.

Direction of arrival measurements at UHF

Electronics Letters, 1989
Direction of arrival measurements have been made at 870 MHz in an urban environment. Examples are given showing the multipath components arriving at the receiver after reflection and scattering from buildings. A synthetic aperture technique is used to measure the directions of arrival.
