摘要:
A definitive method for the calculation of the bistatic radar scattering cross section of a cloud of randomly oriented conducting wire dipoles has been developed by Dedrick et al. [6]. It is based on a Stokes parameter formalism, thus containing complete information regarding transmitter and receiver polarizations. Since the single-wire cross section exhibits strong resonance effects, it is of interest to investigate to what extent these resonance phenomena are affected by the orientation average in a cloud of randomly oriented wires. To study this question, we present comprehensive three-dimensional graphs of the relevant bistatic cross sections plotted versus scattering angle and frequency, as well as of the various polarization functions, using the Einarsson wire cross section. The results indicate the degree to which the resonance features persist in both cross section and polarizations after orientation averaging.
