锥柱复合目标量子雷达散射截面分析

Analysis of Quantum Radar Cross Section of Conical Composite Target

针对导弹目标量子雷达散射截面的计算问题,用锥柱复合模型模拟导弹目标几何结构,引入单光子波动方程,推导和改进量子雷达散射截面表达式.通过干涉分析镜面上原子与光子的相互作用,在检测点测量光子被目标原子散射后的强度,得到锥柱复合目标量子雷达散射截面公式.仿真结果表明:在不同入射角条件下,单光子量子雷达散射截面主瓣峰值高于经典雷达散射截面,而量子雷达散射截面旁瓣峰值低于经典雷达散射截面;随着波长减小,量子雷达散射截面逐渐降低,入射角对量子雷达散射截面无影响.表明量子雷达对小目标具有很高的探测识别能力,分辨率能够达到纳米级,为导弹目标识别提供了依据.

Aiming at the quantum radar cross section computational problems of missiles,a cone-pillared composite model is used to simulate the missile target geometry.The single-photon wave equation is introduced to derive and improve quantum radar cross section expressions.By interfering with the interaction of atoms and photons on the mirror surface,the intensity of the photons scattered by the target atoms is measured at the detection point to obtain the quantum radar cross section formula of the cone column compound target.The simulation results show that the mainlobe peak of single-photon quantum radar cross section is higher than that of classical radar cross section and the quantum radar cross section sidelobes peak is lower than that of classical radar cross section under different incident angles.The quantum radar cross section decreases with decreasing wavelength,and the incident angles have no influences on quantum radar cross section.It shows that the quantum radar has a high detection and identification ability for small targets and the resolution can reach nanometer level,which provides a basis for missile target identification.
