摘要
文章采用后向散射能见度测量法,通过测量激光在大气传输过程中产生的后向散射信号,计算大气的消光系数,从而得出大气能见度值,从硬件和软件上设计,并进行了实验。
Basing on laser backward scattering method, the backward scattering signal of digital receiver is measured in the laser's transmission. Visibility is calculated with the help of the measurement of atmosphere extinction coefficient. The performance of the method is analyzed using both hardward and software, and also realized through experiments.
