【摘要】：利用10個方程對拉曼激光雷達系統(tǒng)獲得的原始數據進行標定,進而反演溫度,并分別與同時刻、同有效對等高度層的標準溫度進行定性對比。選取50組樣本,從定量分析(相似性評判、相差性評判,以及綜合評判)角度,通過權重系數篩選、誤差診斷以及標準化處理等手段對這些樣本開展特征統(tǒng)計,篩選出每一級的質量評判參數與分析方法。所獲取的各級評判標準均基于較大量樣本庫,可以較好地代表激光雷達測溫的平均性能。實驗樣本庫之外的實時探測樣本檢驗表明,綜合多級質量控制技術可有效地描述雷達測溫數據的優(yōu)劣;在不同天氣背景下激光雷達的測溫效果存在差異。
[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.
