Characterization of forward scattering parameters from an arbitrarily shaped cylinder by near-field probing Academic Article uri icon

abstract

  • The forward scattering from an arbitrarily shaped cylinder is characterized by its scattering pattern and the induced field ratio (IFR). Accurate calculation of these parameters for arbitrarily shaped and composite beams is in many cases time consuming, therefore analytical approximations are used. A combined experimental and numerical procedure for evaluation of these parameters based on near-field probing is presented as an alternative. This procedure is shown to be far more accurate than the analytical approximations presently used in calculations of the total scattering effect of tuned sandwich radomes. The results obtained by this method verify well with the scattering characteristics computed analytically or numerically by the method of moments. >
