雾霾粒子对量子干涉雷达探测性能的影响及仿真

Effect of Haze Particles on Detection Performance of Quantum Interferometric Radar and Simulation

为了研究雾霾粒子对量子干涉雷达的影响,结合米氏(Mie)散射理论和标准伽马分布,对雾霾环境下量子干涉雷达探测光子偏振特性、雾霾粒子消光特性进行了分析。针对不同质量浓度的雾霾粒子,建立了量子链路衰减与量子干涉雷达探测光子传输距离之间的关系模型并进行仿真;针对不同的发射波束光子数,建立了雾霾粒子质量浓度与量子干涉雷达分辨率、灵敏度之间的关系模型并进行仿真。实验结果表明,当雾霾粒子质量浓度一定时,量子干涉雷达的分辨率会随发射波束光子数的增多而增大,而其灵敏度随光子数的增多而降低。因此,雾霾粒子对量子干涉雷达的探测性能有显著影响。仿真结果可为研究量子干涉雷达在雾霾天气中的探测效率提供一定参考依据。

To investigate the impact of haze particles on quantum interferometric radar,we examine the correlation between the polarization characteristics of photons detected by quantum interferometric radar and the extinction features of haze particles in a hazy environment,by integrating the Mie scattering theory with the standard gamma distribution.For varying mass concentrations of haze particles,we establish and simulate relationship models between quantum link attenuation and the transmission distance of quantum interferometric radar detection photons.Similarly,for different quantities of photons in the transmitted beam,we develope and simulate relationship models between mass concentration of haze particles and the resolution and sensitivity of quantum interferometric radar.The experimental results reveal that,under a constant mass concentration of haze particles,the resolution of quantum interferometric radar increases with the augmentation of the number of photons in the emitted beam,while its sensitivity decreases with the rise in photon count.Hence,haze particles exert a substantial influence on the detection performance of quantum interferometric radar.These simulation outcomes provide certain reference basis for investigating the detection efficiency of quantum interferometric radar in hazy weather conditions.
