An array virtual extension method for power equipment acoustic emission direction of arrival estimation based on high‐order cumulants

Abstract The performance of array‐based power equipment acoustic emission (AE) source directional of arrival (DOA) estimation methods is decided by not only algorithm performance, but also the array hardware parameters, that is, array aperture, sensor number, and so forth. Improving the estimation p...
