摘要
基于物理光学下散射场计算公式,本文进行了雷达波入射方向对翼面散射能量分布影响的研究及翼面几何形状改变对散射能量分布影响的研究,提出了使翼面外形主要尺寸满足sinc函数零点要求或满足sinc函数旁瓣要求以减小雷达散射截面的整形理论。同时在一定鼻锥范围内雷达散射截面最小的要求下,求解并绘制了最佳外形尺寸设计的范围曲线。
Based on the scattering formulation of the physical optics,the distribution of the scattering energy determined by the variations of incident radar wave direction and main shape sizes is studied and the integration theory of shaping is put forward in the paper.It is concluded that the optimum sizes of two-dimensional wing shape should be satisfied with the zero point requirement of the sinc pattern and the sidelobe requirement of the same pattern. As the results of simulations, the curves of optimum size ranges in a two-dimensional model wing's shaping are computed and drawn out.
