Abstract
A device for obtaining vehicle electromagnetic signature data from electromagnetic signals includes means (16) for obtaining a digitized signal from measured electromagnetic signals. The device further includes means (20) for determining if a digitized signal is a vehicle electromagnetic signature signal. The means (20) then calculate electromagnetic signature data of a vehicle from the digitized signal, and time-stamp each data point of the electromagnetic signature. Vehicles can therefore be classified in accordance with several criteria by specific processing of the digitized electromagnetic signature signals.
