摘要

本文采用基于封闭积分的TDSBR方法计算了典型大型海洋目标的复合时域散射特性。该方法突破了传统建模方法对建模斑块大小的限制。通过傅里叶变换可以快速计算得到复合目标的宽带散射特性。通过分析不同入射条件下的计算结果，探讨了海景中目标与海面的耦合散射以及粗糙海面与入射波的相互作用对目标散射回波的影响。

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.
