| 摘 要： | 为了实现非视线激光大气散射通信,根据米氏散射理论,建立了非视线通信链路模型,研究了1.06m激光的大气散射通信技术,分析了激光接收功率、激光发射功率、激光发散角、接收视场、探测器灵敏度、发射机倾角、接收机倾角、大气衰减和通信距离的关系,并搭建了试验原理系统,进行了1km距离的散射通信试验,获得了激光散射信号。结果表明,在一定的天气条件下,采用波长为1.06m的红外激光进行信号传输,有望实现远距离的大气散射通信。

| Abstract: | In order to realize non-line-of-sight (NLOS) laser scattering communication in atmosphere, the NLOS communication link model was founded according to Mie scattering theory and 1.06m laser scattering communication in atmosphere was studied. The relationship of laser receiving power, laser transmitting power, laser beam divergence angle, receiver field of view, detector sensitivity, emission inclination angle, receiver inclination angle, atmosphere attenuation and communication distance were analyzed. After establishing the experimental system, an experiment of 1km scattering communication was taken on and laser scattering signal was gotten. The experimental result shows that atmosphere scattering communication at long distance can be realized by choosing 1.06m laser for signal communication under a certain weather condition. |
