摘要

The Gabor expansion is used to reconstruct the scattering pattern and the induced field ratio (IFR) of an arbitrarily-shaped cylinder measured in a focused beam system. The fields of the transmitting and receiving antennas in the measurement system are described by equivalent fundamental Gaussian beams. The results obtained by the proposed method agree well with the scattering characteristics computed analytically or numerically by the method of moments (MoM), finite elements method (FEM) and by a previous method of analysis using an FFT algorithm.
