Özet:

 

Realistic high frequency surface wave radar (HFSWR) targets  are investigated numerically in terms of electromagnetic wave --  target interactions.  Radar cross sections (RCS) of these targets are  simulated via both the finite-difference time-domain (FDTD) method and  the Method of Moments (MoM).  The virtual RCS prediction tool that was  introduced in previous work is used for these investigations.  The  virtual tool automatically creates the discrete FDTD model of the  target under investigation and performs the FDTD RCS analysis.  It  also automatically constructs a MoM wire grid model of the target;  therefore, it is also possible to compare FDTD results against the  MoM-based NEC (Numerical Electromagnetic Code) data.  Bi-static RCS  patterns under a variety of illuminations over the whole HF band (3-30  MHz) are presented.  The mono-static RCS vs.  frequency of these  targets is also given.
