摘要
研究了目标在聚焦口径天线焦点的散射问题。以一个金属目标和一个理想口径组成的系统为例，阐明了这类散射问题的电磁过程。研究结果表明，选择适当的口径分布，可以大大提高目标回波强度。文中给出大量计算结果，并对不同的口径分布做了比较，得到了若干具有工程意义的重要结论。
This paper discusses the backscattering by a target placed in the focal plane of a focused aperture.A system consisting of a conducting target and an ideal aperture antenna is used to illustrate the electromagnetic process.The research result indicates that if the aperture distribution is properly chosen,the radar return can be greatly enhanced.The calculated results are presented and a comparison is made regarded to the power received by the aperture,and some useful results for engineering practice aree achieved.
