Forward Parametric Modeling Based on Target Attribute Scattering Center Model
The target attribute scattering center is parametrically modeled for automatic identification of the radar targets. Before generating the model, high-precision geometric modeling is applied based on the decomposition of the solid parts, and a set of ray tracing methods exhibiting spatial ray diversity is proposed. Based on this ray tracing step, a set of parametric forward-modeling methods is developed for estimating the center of scattering based on the spatial ray diversity. Further, the center of the strong scattering source with respect to the target edge is added on the basis of the already extracted surface scattering source. The model parameters are also derived during this additive process. The results obtained using this method are compared with those obtained using the typically used high-frequency method, confirming the effectiveness of the parametric model. Thus, the proposed method for parametric modeling provides a new auxiliary mechanism for compiling the radar target features.
