摘　　要：针对当前环境下空气质量较差、污染较为严重问题,提出基于无线传感器的遥感监测技术来实现有效解决。通过指标评价分析大气环境中可能出现的污染源浓度,确定对应污染等级。研究光源照射下光谱能量与气体分子间关系,建立光谱吸收雷达检测大气中高分子量细微颗粒以及其他异常物质颗粒。将颗粒物分子能量以谱线的形式完成量化,通过光谱折射的波长及截面判定是否符合污染物分子含量标准,如果符合判定为污染物,完成监测。实验证明,所提方法监测的数据准确率都较高,整体误差保持在可控范围之内。Aiming at the problems of poor air quality and serious pollution in the current environment,a remote sensing monitoring technology based on wireless sensor is proposed to solve them effectively.The concentration of possible pollution sources in the atmospheric environment is analyzed through index evaluation to determine the corresponding pollution level.The relationship between spectral energy and gas molecules irradiated by light source is studied,and a spectral absorption radar is established to detect high molecular weight fine particles and other abnormal material particles in the atmosphere.The molecular energy of particles is quantified in the form of spectral lines.Whether it meets the pollutant molecular content standard is determined by the wavelength and cross section of spectral refraction.If it meets the standard,it is determined as a pollutant,and the monitoring is completed.Experiments show that the data accuracy of the proposed method is high,and the overall error is kept within a controllable range.
