碘分子滤波器温度对风速测量精度的影响

通过理论模拟碘分子的吸收曲线。模拟出不同回向散射比Rb(r)的大气回波信号和碘分子滤波器透过率函数R(r,ν)卷积的光谱曲线;该曲线与碘分子滤波器的温度有关。模拟碘分子滤波器的温度变化,在同时测量气溶胶和大气分子散射的情况下,获得测量误差随碘分子滤波器温度变化的曲线。最后,设置适当的碘分子滤波器温度,采用青岛海洋大学遥感研究所研制的非相干多普勒激光测风雷达系统测量回向散射比Rb(r)和回向散射信号频移的距离剖面,反演出风速和探空气球的测风数据比较。测量风速的标准偏差为0.985 m/s。

The Effect of Idine Molecule Filter temperature to Wind Field Measurement

This paper simulates the absorbing curve, atmospheric backscattering signal of different backscattering ratio , and the spectrum curve of Idine molecule filter permeance function . It has been proved to have relation to the temperature of Idine molecule filter. And then this paper achieves the error curve by changing the temperature. Lastly this paper sets the appropriate temperature and the wind field can be retrieved from the field measurement wind system, which is developed by ocean university of China. The error of wind speed is 0.985m/s by compared with sounding balloon.
