摘要

本文旨在研究. 基于Mie粒子散射理论, 运用模拟离散随机分布粒子对光子多重散射的蒙特卡罗方法, 对不同能见度及不同粒子带电量的沙尘大气的微波衰减进行分析. 根据量子照明雷达理论, 采用基于分束器理论的分光链路模型模拟沙尘大气信道, 并根据量子雷达方程及量子检测错误概率理论, 开展不同能见度带电沙尘大气对微波量子照明雷达的检测错误概率、信噪比和最大探测范围等影响研究, 并与经典TMN雷达性能进行对比分析. 结果表明, 在沙尘大气中, 量子照明雷达的性能随着能见度的增大而提高, 粒子带电会引起信号衰减增大及系统性能下降, 带电量的变化引起性能的改变是非线性的. 当能见度较高时适当提高信号频率可提高量子照明雷达的性能, 当能见度较低时频率提高带来的增益会小于衰减增大带来的性能下降, 这种情况不宜增大频率. 在与经典雷达的比较发现, 在较低能见度及较低发射平均光子数时量子雷达性能较优, 但随着光子数增加, 优势逐渐降低.

Abstract

This work is to study the effects of charged sand/dust atmosphere on the performances of microwave quantum illumination (QI) radar. Based on Mie particle scattering theory, using a Monte Carlo method for simulating the physical process in which photon is scattered multiple times by discrete random distributed particles, the specific attenuation (dB/km) of microwave propagating in sand/dust atmosphere are analyzed under the conditions of varying atmospheric visibility and sand/dust particles with different charged quantities. It is indicated that the specific attenuation obtained by multiple scattering is smaller than that obtained based on Mie theory, for microwave propagating in charged sand/dust atmosphere. The smaller the atmospheric visibility, the greater the difference is, while the difference decreases gradually as the atmospheric visibility increases. Then, it is more reasonable to consider multiple scattering attenuation at lower atmospheric visibility. When sand/dust particle is charged, the specific attenuation is increased, however, this increase is not linear. According to quantum illumination radar theory, a beam splitter-based optical link model is used to simulate the sand/dust atmospheric channel. The effects of charged sand/dust atmosphere with different visibility on the detection error probability, signal-to-noise ratio, and maximum detection range for microwave quantum illumination radar are studied by using quantum radar equation and quantum detection error probability theory. The performances between QI radar and classical two-mode noise (TMN) radar are compared and analyzed. These results show that the performances of quantum illumination radar are improved with sand/dust atmospheric visibility increasing. When sand/dust particles are charged, the performances for QI radar are degraded due to attenuation increasing. The change in the performance is nonlinear with the variation of sand/dust carrying charge quantity. When visibility is high, increasing the signal frequency can improve the performance of quantum illumination radar, but when visibility is low, the gain of frequency increase is offset by the performance decline caused by attenuation increase. Therefore, it is not recommended to increase the frequency in such a case. The comparison with classical radar reveals that QI radar performs better under the condition of lower atmospheric visibility and lower average photon emission, but this advantage diminishes as the number of photons increases. In a word, these results show that the performances of QI radar are more significant at lower atmospheric visibility. Under higher visibility conditions, the QI system SNR can be improved by increasing frequency. The maximum detection range of the QI radar is significantly better than that of the classical TMN radar.
