【摘要】：利用10个方程对拉曼激光雷达系统获得的原始数据进行标定,进而反演温度,并分别与同时刻、同有效对等高度层的标准温度进行定性对比。选取50组样本,从定量分析(相似性评判、相差性评判,以及综合评判)角度,通过权重系数筛选、误差诊断以及标准化处理等手段对这些样本开展特征统计,筛选出每一级的质量评判参数与分析方法。所获取的各级评判标准均基于较大量样本库,可以较好地代表激光雷达测温的平均性能。实验样本库之外的实时探测样本检验表明,综合多级质量控制技术可有效地描述雷达测温数据的优劣;在不同天气背景下激光雷达的测温效果存在差异。
[Abstract]:The original data obtained from Raman lidar system were calibrated by 10 equations, and the temperature was retrieved, and compared qualitatively with the standard temperature of the effective equal height layer at the same time. 50 groups of samples were selected. From the point of view of quantitative analysis (similarity evaluation, difference judgment, and comprehensive evaluation), the characteristic statistics of these samples are carried out by means of weight coefficient screening, error diagnosis and standardized treatment. The quality evaluation parameters and analysis methods of each level are screened out. The obtained evaluation criteria are based on a large sample base, which can represent the average performance of lidar temperature measurement. The real-time detection sample test outside the experimental sample database shows that, Integrated multi-stage quality control technique can effectively describe the merits and demerits of radar temperature measurement data, and the effect of lidar temperature measurement is different in different weather background.
