The Analysis of Mainlobe-Slumping Quantum Effect of the Cube in the Scattering Characteristics of Quantum Radar

As the core characters in the scattering characteristics of quantum radar, the quantum radar cross section (QRCS) has some distinct properties from the classical radar cross section (CRCS) on two-dimensional (2D) targets, such as the quantum interference effect of sidelobe. However, due to the ability of the algorithm only for 2D targets basically, there is not sufficient work on the quantum effect in the scattering characteristics of quantum radar for three-dimensional (3D) targets, especially for other effects. Here we report a novel mainlobe-slumping quantum effect of the cube in the scattering characteristics of quantum radar with an improved algorithm for the 3D targets. In addition, it has a completely different physical origin from the classic radar scattering. Further, we analyze the source of this sudden decreasing in the curve of QRCS based on the quantum theory and simulation data. We conclude that this kind of new macroscopic quantum phenomenon can be used in the detection and discrimination of stealthy weapons and biomedicine.
