A Forward Approach to Establish Parametric Scattering Center Models for Complex Dielectric Targets

This paper proposes a forward approach to establish parametric scattering center models for complex dielectric targets. It proposes a space ray diversity method for complex medium targets based on ray splitting tracing method. Based on the high frequency electromagnetic mechanism of complex targets, a method of calculating the equivalent action point of internal coupling action ray is proposed. This solves the problem of the forward calculation of the three-dimensional position parameters of the scattering center. Finally, the decomposition and its quantitative characterization technique of strong scattering source for complex dielectric targets are obtained, and the target scattering center model with complex dielectric has been established with clear and accurate scattering mechanism. This method greatly expands the scope of target application in the forward modeling method of attribute scattering center. Finally, a simplified wing calculation example shows the feasibility and effectiveness of the proposed method.
