Abstract
A device for obtaining vehicle electromagnetic signature data from electromagnetic signals includes means () for obtaining a digitized signal from measured electromagnetic signals. The device further includes means () for determining if a digitized signal is a vehicle electromagnetic signature signal.

Vehicles can therefore be classified in accordance with several criteria by specific processing of the digitized electromagnetic signature signals.
