Description
Summary:The conception of scattering center (SC) is mostly used to cope with and deal with radar target recognition problems. The multi-solvability of the target SC model, in the inverse extraction process, should be effectively limited, and the SC cannot be simply regarded as an equivalent scattering source. To provide a more comprehensive explanation of the components' scattering in the high-frequency region, in this paper, the Stratton-Chu formulation's physical significance is revisited, with a full interpretation of the correspondence between the induced current and the high frequency scattering mechanism. The analysis of inherent phase demonstrates the theoretical basis for quantitative exploring the physical properties of SC position. The study focuses on the component-level SC, meaning that the canonical geometric structure is analyzed as a whole for scattering contributions. During the demonstration, methods for predicting the 3-D position of SC are presented for two scenarios: presence or absence of specular reflection points.
