Direction of Arrival and the Rank-Revealing URV Decomposition [PDF]

open access: yes, 1998
In many practical direction-of-arrival (DOA) problems the number of sources and their directions from an antenna array do not remain stationary. Hence a practical DOA algorithm must be able to track changes with a minimal number of snapshots.

Space-time division cluster DoA estimation algorithm based on UWA spread spectrum signal

open access: yesTongxin xuebao, 2022
To solve the problems of poor stability, low resolution, and performance degradation under low signal-to-noise ratio (SNR) of the direction of arrival (DoA) estimation, a space-time division cluster (STDC) DoA estimation algorithm was proposed for under ...
