Abstract
A processor-implemented method for direction-of-arrival estimation. The method includes: receiving a plurality of input signals at a sensor array, each sensor having an angle estimator and a cross-spectra term; transforming the input signal from each of the plurality of sensors to the time-frequency domain using a short-time Fourier transform; constructing a Perpendicular Cross-Spectra Difference (PCSD) for each of the plurality of angle estimators associated with each sensor for each frequency bin and time index; calculating an auxiliary observation for each of the angle estimators; and determining an impinging angle for each of the angle estimators based on the auxiliary observation.
