Near-Field Analysis of Broadband Scattering

In this paper, the broadband near-field scattering characteristics of targets are analyzed. Plane wave and double-ridged horn antenna are used respectively in 13GHz for near-field scattering analysis. Time-domain response of scattering objects are investigated firstly, and the waveform and time-delay are presented. Furthermore, near-field scattering coefficient (NFSC) and Generalized RCS (GRCS) are also introduced to analyze the near-field scattering characteristics of objects. Finally, four time domain characterization parameters are designed to quantitatively analyze the time domain waveform of scattering objects.
