Multi-azimuth wide-band scattering characteristics analysis of large-scale targets on the sea

In this paper, the TDSBR method based on closed-form integration is used to calculate the composite time-domain scattering characteristics of typical large marine targets. This method breaks through the limitation of traditional modeling methods on the size of modeling patches. It can perform fast calculations and then obtain the wide-band scattering characteristics of composite targets by Fourier transform. By analyzing the calculation results under different incident conditions, the effects of the coupled scattering between the target and the sea surface in the sea scene and the interaction between the rough sea surface and the incident wave on the target scattered echo are explored.
