Blind Calibration of Sparse Arrays for DOA Estimation with Analog and One-bit Measurements

ICASSP 2019accepted

In this paper, the focus is on the gain and phase calibration of sparse sensor arrays to localize more sources than the number of physical sensors. The proposed technique is a blind calibration method as it does not require any calibrator sources. Joint estimation of the gain errors, phase errors, a…

Blind Calibration for Acoustic Vector Sensor Arrays

ICASSP 2018accepted

In this paper, we present a calibration algorithm for acoustic vector sensors arranged in a uniform linear array configuration. To do so, we do not use a calibrator source, instead we leverage the Toeplitz blocks present in the data covariance matrix. We develop linear estimators for estimating sens…
