Is Power Averaging the Best Estimator for Undersea Acoustic Data?

Abstract

The power average is the statistic which is commonly used in all types of acoustic data processing. It is an excellent estimator for 11 Well behaved11 Gaussian distributions when the central or average value is desired. However, when there are 11 outliers11 and errors or when the distributions are not Gaussian there are other statistics which are better estimators.
