摘要: 为了研究带电沙粒对量子干涉雷达(QIR)性能变化的影响机制, 首先根据沙粒在电场中的电荷分布和消光系数, 建立了沙粒参量与QIR链路衰减的关系; 随后在不同光子数下, 分别仿真研究了球形、椭球形带电沙粒的不同参量对QIR分辨率、灵敏度及最优灵敏度的影响。仿真结果表明, 随着带电球形沙粒荷质比、带电椭球形沙粒等效半径及粒子质量浓度的增加, QIR链路衰减增大; 而当探测光波长和带电沙粒的参量影响一定时, 随着光子数的增加, QIR的分辨率随之提高, 灵敏度先增大后降低。由此可见, 带电沙粒的消光效应对QIR性能的影响不可忽略, 仿真实验结果可为QIR技术在沙尘天气中进行目标探测的应用和发展提供理论参考。

Abstract: To investigate the performance change and influence mechanism of quantum interference radar (QIR) system under the influence of charged sand particles, the relationship between charged sand particles and quantum link attenuation of QIR is established firstly based on the charge distribution and extinction coefficient of sand particles in an electric field. And then, the influences of different parameters of charged spherical and ellipsoidal sand particles on the resolution and phase sensitivity of the QIR are simulated under different photon emission numbers. The simulation results show that the QIR quantum link attenuation tends to increase with the increase of the charge-to-mass ratio of charged spherical sand particles, the equivalent radius of charged ellipsoidal sand particles, and the particle mass concentration. And under the given wavelength and the parameter influence of the charged sand particles, increasing the number of emitted photons will improve the QIR resolution and decreases the QIR sensitivity. It can be seen that the influence of the extinction effect of charged sand particles on the QIR performance cannot be ignored, and the simulation results can provide theoretical support for the further development and application of QIR technology in detecting targets in dusty weather.
