In this paper, a Fourier expression of the quantum radar cross section (QRCS) of a dihedral corner reflector is proposed, which avoids the problems caused by atomic sampling on the target-object surface and is a powerful tool for analyzing the scattering characteristics of the reflector. We compare the result of the proposed expression with that of numerical calculations, and have preliminarily verified its correctness. On this basis, we discuss the influence of the wavelength of single photon pulses and the panel size of a dihedral corner reflector on QRCS in detail. Simulation results demonstrate that from a single factor of wavelength, a quantum radar using a small-wavelength quantum signal has better visibility to the reflector, and the quantum scattering intensity is proportional to the panel size. Compared with classical radar, quantum radar has an enhanced detection performance that is more stable within a wide angle range, which is insensitive to the wavelength of the quantum signal and panel size of the reflector and is helpful for the detection of stealth targets.

二面角反射器量子雷达截面的傅立叶表达式


本文提出了二面角反射器量子雷达截面（QRCS）的傅里叶表达式，避免了目标-物体表面原子采样带来的问题，是分析目标物散射特性的有力工具。反射器。我们将所提出的表达式的结果与数值计算的结果进行了比较，初步验证了其正确性。在此基础上，详细讨论了单光子脉冲波长和二面角反射器面板尺寸对QRCS的影响。仿真结果表明，从波长的单一因素来看，使用小波长量子信号的量子雷达对反射板具有更好的可视性，并且量子散射强度与面板尺寸成正比。与经典雷达相比，量子雷达具有增强的探测性能，在大角度范围内更加稳定，对量子信号的波长和反射器的面板尺寸不敏感，有助于隐形目标的探测。
