In this study, we develop the calculation models for single and double scattering of dihedral corner reflectors and obtained the QRCS expression for dihedral corner reflectors of any structure. The simulation results demonstrate that the center of QRCS mainly exhibits double scattering characteristics, while the edge exhibits single scattering characteristics. Dihedral corner reflector with acute dihedral angle has stronger scattering intensity in the edge. However, the QRCS of the obtuse dihedral corner reflectors show an obvious single scattering peak, which approaches to the bisector as the dihedral angle increases. When detecting dihedral corner reflectors with different size ratios, the side with a larger facet has a higher detection probability. The characteristics of dihedral corner reflectors in experiments provide specific guidance for quantum radar to detect targets with dihedral.

二面角反射器的量子雷达截面分析

在本研究中，我们开发了二面角反射器单次和双次散射的计算模型，并获得了任何结构的二面角反射器的 QRCS 表达式。仿真结果表明，QRCS的中心主要呈现双散射特性，边缘呈现单散射特性。锐角的二面角反射器在边缘具有更强的散射强度。然而，钝角二面角反射器的QRCS显示出明显的单散射峰，随着二面角的增加接近平分线。在检测不同尺寸比例的二面角反射器时，面较大的一侧检测概率较高。
