Multi-path couplings measurements and simulations of typical objects in complex near-filed condition

Based on the shooting and bounding rays (SBR) method which is split into physical optics (PO) and geometrical optics (GO), the near-filed scattering of the typical objects in complex environment is simulated. Multi-path cases of the reflection geometry are considered to account for effects of the targets, surroundings and antenna aspect angles in near-field regions. Then the complex-valued scattering response is derived. Numerical examples and measurement examples are carried out to give the conclusions of the multi-path couplings characters in near-filed regions. The comparison on the numerical results and measurement results shows an acceptable error. The proposed method in this work is very effective on solving the coupling and Multi-path problem in project and academic.
