Application of the improved IPO algorithm in electromagnetic scattering

An Iterative Physical Optics (IPO) algorithm combined with neural network decoupling is proposed to improve the calculation accuracy of electromagnetic scattering from large vessels. Based on the PO (Physical Optics) algorithm, this method mainly considers the self-coupling factor of surface elements in the IPO algorithm, improves the threshold value W method, and finally performs neural network decoupling. The electromagnetic calculation analysis of bulk carriers, container ships, passenger ships and oil tankers shows that the improved IPO algorithm improves the calculation accuracy of Radar Cross Section under the condition of ensuring the calculation speed. threshold value of IPO algorithm to the adaptive.
