内容简介:利用物理光学迭代法独立设计程序,采用前后向算法并结合欠松弛因子加速收敛,提高运算效率.通过计算简单标准模型的雷达散射截面(RCS)验证了程序的可靠性.在此基础上,对两种不同宽高比二元喷管简化模型及轴对称喷管简化模型的RCS进行了计算并加以分析比较.结果表明,程序具有较好的计算精度和通用性,在较大范围的姿态角内,二元喷管简化模型的RCS高于轴对称喷管简化模型的RCS.

Abstract:The iterative physical optic method was used for the programming code to cai culate radar cross section (RCS), while the forward-backward algorithm combined with relaxation factor was used to accelerate the convergence and improve operation efficiency. Some sample standard models were calculated to validate the reliability of the code; based on this, the RCS of two dimensional (2-D) nozzles with different aspect ratios and an axisym metric nozzle was computed and compared. According to the numerical results, this proce dure has high accuracy and versatility, and the RCS of the 2 D nozzle is higher than that of the axisymmetric nozzle in the large angular range.
