DOA Estimation Algorithm of UWB Signal Based on Unitary Circuit Array
In this contribution, unitary circular array (UCA) techniques for estimating Direction of Arrival (DOA) of Ultra wideband (UWB) propagation signals are studied. 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-RBMUSIC algorithm is proposed, which can estimate 360 degree unfaintness azimuth angles.
