A Decoupled Direct Positioning Algorithm for Strictly Noncircular Sources Based on Doppler Shifts and Angle of Arrival

open access: yesIEEE Access, 2018
This paper discusses the localization problem for strictly noncircular sources based on Doppler shifts and angle of arrival (AOA). The conventional location methods, called two-step methods, first extract measurement parameters from the signals, and then

Spatial pseudorandom array processing [PDF]

open access: yesIEEE Transactions on Acoustics, Speech, and Signal Processing, 1989
A pseudorandom permuting procedure and the associated array signal processing are introduced for resolving multiple coherent signal sources. Conventional adaptive beamforming algorithms fail to operate in such a situation, as their performance will degrade.
