Target identification with polarization dependent transfer functions

Abstract

In this paper the scattering behavior of two electrically conducting objects (sphere and cylinder) will be described. The objects have been illuminated by a quasi-monostatic ultra-wideband (UWB) radar system. Using very short pulses the transfer function of the targets could be calculated over a wide range of frequencies. Besides the frequency dependence the influence of the polarization was investigated. This allowed the target identification by using only A-scans in two different polarization planes. Furthermore, geometrical parameters of the targets, e. g., the diameter, could be determined from the calibrated data easily.
