通用化电磁散射靶船的建模与RCS计算

内容简介：通过对国外多型现役舰艇舰体、舰载设备的分析,总结出其外部形体特征,建立了通用化、模块化电磁特性靶船模型,综合应用高频RCS分析方法,如物理光学法、一致绕射理论等,对该模型及其缩比模型的RCS进行了计算。对比缩比模型的计算结果和真实测量结果,证明RCS计算结果准确,模型反映了真实靶船的电磁散射特性,满足工程设计需要。

Abstract：Based on the analysis of body and shipboard equipments of many foreign ships in service,this paper sums up the external body characteristics of the ships,sets up the target ship model of generalized and modular electromagnetic characteristic,applies the high-frequency radar cross section（RCS） analysis methods such as physical optics method,uniform theory of diffraction（UTD）,etc.,calculates the RCS of this model and its micro-ratio model.Comparing the result of micro-ratio model with the real measurement result,the calculation result of RCS is accurate,the electromagnetic scattering characteristics of the real target ship can be reflected through the model,which satisfies the needs of engineering design.
