Analysis of Quantum Radar Cross-Section of Dihedral Corner Reflector

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.
