摘要
以激光信号在传输介质中的布里渊散射频移量模型为基础,依据相关大气数据建立基于布里渊散射信号检测的大气探测模型。该模型中布里渊频移量只与大气高度相关,详细描述了低空大气范围内布里渊频移量的连续分布状态。结果表明在0~86 km的海拔高度范围内,大气的布里渊散射频移量分布在1.0~1.3 GHz之间。与有关数据相比,该模型与实际情况非常符合,同时具有很好的连续性和普适性。
Abstract
Based on Brillouin scattering frequency-shift model of laser transmitting through medium and relative atmospheric data, an atmospheric detection model based on detecting Brillouin scattering signal is established. In this model, Brillouin frequency shift is only correlative to the atmospheric altitude. The continuous distribution state of Brillouin frequency shift of low atmosphere is described in detail. The result shows that atmospheric Brillouin frequency shift is distributed from 1.0~1.3 GHz at the altitude from 0~86 km. This model, presents the data agreeing well with practical data and has good continuity and generality.
