Use of modulation spectra for representation and classification of acoustic transients from sniper fire
暂无分享,去创建一个
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.
