Abstract :
Unlike external array calibration, array self-calibration does not assume that source angles of arrival are known. This paper studies novel self-calibration algorithms and tests them on experimental data. Results indicate that self-calibration algorithms based on an appropriate cost function may achieve source-localization performance comparable to that of external array calibration and better than without calibration.
