量子雷达散射截面（QRCS）描述了用少量光子照射物体时获得的回报。然而，以往的研究主要集中在量子雷达的单站散射。本文针对我们提出的双站量子雷达散射截面（BIQRCS）中的四个关键问题，对典型二维平板的BIQRCS进行了计算和分析。首先，如Brandsema所述，得到矩形板的进一步推导的解析解。此外，还得到了入射频率和光子数对平板BIQRCS的影响。此外，我们还首次揭示了在给定入射角下，BIQRCS的旁瓣包络曲线具有频率不变性。最后，我们给出了BIQRCS，经典的雷达截面（CRCS），单站QRCS的平板之间的一些比较结果，并找到了BIQRCS的旁瓣在给定的方向上的优势。我们预计，这些研究成果将发现在隐身平台的检测和歧视的使用。
The quantum radar cross section (QRCS) describes how much return one gets when illuminating an object with a handful of photons. However, the previous studies mainly focused on the monostatic scattering of quantum radar. In this study, in response to the four key questions raised by ourselves in bistatic quantum radar cross section (BIQRCS), we calculate and analyze the BIQRCS for the typical tow-dimensional plate. First, as mentioned by Brandsema, the further derived analytical solution for the rectangular plate is obtained. In addition, the influence of incident frequency and the number of photons on the BIQRCS for the plate were obtained. Besides, we first reveal that the envelope curves of sidelobes in BIQRCS at the given incidence display the invariance in frequency. Finally, we show some comparison results among the BIQRCS, classical radar cross section (CRCS), and monostatic QRCS for the plate and find the advantage of sidelobe of the BIQRCS in given direction. We anticipate that these research results will find use in the detection and discrimination of stealthy platforms.
