Abstract

In previous work, we have given a method for obtaining propagation invariant features for classification of underwater objects from their sonar backscatter in dispersive but rangG'-independent environments. In this paper we consider the derivation of invariant features for classification in range dependent environments, based on the parabolic equation.
