摘要:: 为了解决船舶电大尺寸目标计算速度慢、内存需求量大、仿真周期长等问题，利用大面元物理光学（large element physical optics，LE-PO）算法，通过计算机仿真，建立油船、散货船两种船舶的三维模型，分析总结输入不同极化方式、不同频率、不同入射角以及不同船首向对RCS（radar cross section）的影响。研究结果表明，大面元物理光学法(LE-PO)可完成船舶电大尺寸目标的电磁分析计算，可为油船、散货船的目标识别提供理论参考依据。

Abstract:: In order to solve the problems such as slow calculation speed,huge memory demand and long simulation cycle of electrically large target ships,LE-PO (large element physical optics) algorithm was used to build three dimensional models of oil tanker and bulk carrier through computer simulation.The influence of different polarization modes,different frequencies,different incidence angles and different bow inputs on the RCS (radar cross section) is analyzed and summarized.The results show that the large element physical optics method (LE-PO) can realize the electromagnetic analysis and calculation of electrically large target ship,and provide a theoretical reference for target identification of oil tankers and bulk carriers.
