Abstract

Unobtrusive determination of an intruding vehicles length is useful for threat assessments in perimeter surveillance, law enforcement and anti-terrorism applications. We describe a passive radar architecture wherein a broadcast signal from a frequency modulated (FM) radio transmitter is bistatically scattered by a moving vehicle and received and processed in a software defined radio platform. Measurement of the maximum Doppler frequency and the target viewing time combined with the known geometry of the measurement scenario permits the estimation of the target vehicles length. Good agreement is observed between actual and estimated lengths for various vehicle types.
