Abstract

There are many applications for classification of acoustic transients produced by supersonic projectile fire. Analysis of existing models for such transients suggests they have properties which may be well-captured by the transform of a signal into joint acoustic and modulation frequency: a modulation spectral representation. Simple features are extracted from this representation which enables successful use in such an important classification application.
