Analysis of Radar Detection of Agitated Metals (RADAM)
Abstract
The rapid discontinuous fluctuations observed in the scattering from a moving multielement target, known as the intermittent-contact RADAM effect, are produced by variations in the surface currents caused by motion-induced changes in current paths between the target elements. Such a target can be modeled as a loaded scatterer. Tracked vehicles produce very strong and distinctive RADAM modulation at VHF frequencies. The results of experimental studies using a 5:1 scale-model tank suggest that the principal source of the above effect in this type of vehicle is the contact between the drive sprocket and the track. Time-domain processing of the detected amplitude modulation can be used to develop RADAM signatures for tracked vehicles and to identify them in real time.
