Abstract:
The RCS of targets with near-field multi-scattering effect is studied by integrating with graphical electromagnetic computing. It is a complex work to detect the triangle elements which will affect the other triangle elements by producing radiation filed for targets with near-field multi-scattering effect.In order to simplify this process, graphical electromagnetic computing (GRECO) is introduced. After the targets are transformed by rotation and translation, the triangle elements which affect the other elements can be detected conveniently by using GRECO. Then, the near-filed and far-field RCS of canonical objects are computed respectively, and the result is in accordance with the document result and measurement result. The effect of multi-scattering is considered by using GRECO, and the applying area of GRECO is extended from physical optics (PO) to iterative physical optics (IPO).
