摘要:

研究煤烟气溶胶粒子对量子干涉雷达性能的影响，基于煤烟气溶胶粒子的光学特性，探究了粒子数浓度和相对湿度与链路衰减的关系，并分析了煤烟气溶胶粒子对量子干涉雷达探测距离的影响；针对量子干涉雷达的探测原理及结构，讨论煤烟气溶胶粒子对量子干涉雷达生存性能、分辨率及灵敏度的影响并进行数值仿真实验。结果表明：随着煤烟气溶胶粒子数浓度增加、相对湿度减少，量子干涉雷达探测距离及生存性能呈逐渐下降趋势；忽略其他因素的影响，增加光子数，分辨率呈上升趋势，灵敏度在煤烟气溶胶粒子造成的衰减较小时得到提升；当控制参考光与本地光的透过率相近或者相同时，增加光子数可有效提升灵敏度。

Abstract:

To study the effect of soot aerosol particles on the performance of quantum interference radar, based on the optical properties of soot aerosol particles, the relationship between the particle number concentration and relative humidity and link attenuation is investigated respectively, and then the effect of soot aerosol particles on the detection distance of quantum interference radar is analyzed; in view of the detection principle and the structure of the quantum interference radar, the effect of soot aerosol particles on the survival performance, resolution and sensitivity of the quantum interference radar is discussed and numerically simulated. The effect of soot aerosol particles on the survival performance, resolution and sensitivity of quantum interference radar is discussed and numerically simulated. The results show that: with the increase of soot aerosol particle concentration and the decrease of relative humidity, the detection distance and survival performance of the quantum interference radar show a gradual decrease; ignoring other influencing factors, increasing the number of photons, the resolution tends to increase, and the sensitivity is improved when the attenuation caused by soot aerosol particles is small; when the transmittance of the control reference light and the local light are similar or the same, increasing the number of photons can effectively improve the sensitivity.
