Scattering features for target recognition using finite rate of innovation model

This paper uses a recently developed finite rate of innovation estimation model [1] to extract the scattering centers of a radar target. The extracted features are then used in a non-cooperative target identification scheme. The contribution lies in realizing that radar backscatter is not band-limited especially ultra-wideband radar backscatter with impulsive scattering models, and thus cannot be sampled using conventional sampling techniques that assume a band-limited signal.
