High Precise Scattering Centers Models for Cone-Shaped Targets Based on Induced Currents

Based on induced currents of cone-shaped targets, the high precise scattering center model is derived in this paper. The distribution characteristics of the induced currents and their relationships with the attributes of scattering centers are investigated in detail; the high precise scattering center model is obtained. In order to validate the scattering center model, numerical simulations of two cone-shaped targets are presented, and the accuracies of the models are validated through comparing the range profiles simulated by the models with those by a full-wave numerical method. The validation results demonstrate that this model is superior to the existing model in precisely characterizing the scattering centers induced by creeping waves.
