Least-Squares DOA Estimation with an Informed Phase Unwrapping and Full Bandwidth Robustness
ICASSP 2020accepted
The weighted least-squares (WLS) direction-of-arrival estimator that minimizes an error based on interchannel phase differences is both computationally simple and flexible. However, the approach has several limitations, including an inability to cope with spatial aliasing and a sensitivity to phase…
