| 標(biāo)題 |
| Haar小波和最小二乘法在光纖監(jiān)測系統(tǒng)的應(yīng)用(16 卷) |
| 英文標(biāo)題 |
| Application of Haar wavelet and least square estimation in Fiber Monitoring Online System |
| 摘要 |
| 主要研究利用Haar小波變換對OTDR曲線進(jìn)行事件分析。用Haar小波對基于OTDR卡的測試數(shù)據(jù)進(jìn)行分解，對高頻部分進(jìn)行去噪提取奇異點，并在最小二乘法擬合的基礎(chǔ)上，判斷事件位置和類型并計算光纖監(jiān)測系統(tǒng)所需要的參數(shù)。 |
