Method and device for classifying vehicles

   
   

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.

Um dispositivo para obter dados eletromagnéticos da assinatura do veículo dos sinais eletromagnéticos inclui meios (16) para obter um sinal digitado dos sinais eletromagnéticos medidos. O dispositivo mais adicional inclui meios (20) para determinar se um sinal digitado for um sinal eletromagnético da assinatura do veículo. Os meios (20) calculam então dados eletromagnéticos da assinatura de um veículo do sinal digitado, e time-stamp cada ponto de dados da assinatura eletromagnética. Os veículos podem conseqüentemente ser classificados de acordo com diversos critérios processar específico dos sinais eletromagnéticos digitados da assinatura.
