摘要
本文提出一种综合复射线法和几何光学射线法优点的新的平面波射线分解方法，对该方法的拟合误差与参数之关系作了数值分析，对不同应用背景下的展开参数的选取作了说明，该方法可用于开口腔的ＲＣＳ计算，并能有效提高大口径腔体ＲＣＳ计算的效率，同时克服复射线方法受到的腔体深度及曲面曲率的限制。
In this paper, a new method of plane wave simulation of ray pipe is presented, which has the advantages of Geometrical Optic ray and Complex ray. Numerical analysis is made on the relations between the fitting error and simulating parameters. A brief explanation about how to choose simulating parameters under different backgrounds is also given. This method can greatly raise the efficiency of RCS calculation of large open ended cavities. Moreover, it can overcome the limitation of depth and surface curvature of cavities on the complex ray method. [WT5”HZ〗
