ABSTRACT TIME-DELAY SELECTION FOR ROBUST ANGLE OF ARRIVAL ESTIMATION
, 2008 The differences in the arrival times of a signal at spatially separated sensors can be used to estimate the angle of arrival of the signal. Due to noise or sensor malfunction, the time difference estimates may be erroneous and thus the angle of arrival ...
