| 摘 要： | 采用弹跳线法（SBR）对发动机进气道的雷达散射截面（RCS）进行了分析计算。通过光学射线跟踪、场强跟踪及口径积分方法，研究了任意截面和形状的管道电磁散射特性，比较了一实际进气道的计算与实验结果，验证了此方法的有效性，从而解决了工程急需。

| Abstract: | RCS of engine duct is calculated and analyzed using SBR method.EM scattering characteristics of the pipe with arbitary section and shape are studied by the methods of shooting and bouncing rays,field intensity track and aperture integral.The calculation is compared with the experimental result for a real engine duct.It proves that this method is very effective and meets practical needs in engineering. |
