摘要：
In order to further optimize the modeling method of scattering center parametric model, the forward automatic modeling method of scattering center model is carried out based on the geometric model of the target, after the complex structure of the target is partitioned and numbered according to the geometric surface. The automatic method mainly realizes the automatic calculation of model length, position and other parameters. This method can automatically determine the scattering source, scattering mechanism and scattering center model parameters, and improve the modeling efficiency. Firstly, the components of the geometric model are decomposed. Then, the scattering field of the target is simplified as the superposition of partial ray contributions according to the accuracy requirements by using ray tracing and diversity technology, and the automatic calculation of the scattering center model parameters is studied. Finally, a series of scattering center parametric models are calculated and compared with reliable data to verify the effectiveness of the automatic modeling method. © 2021, Editorial Office of Systems Engineering and Electronics.
