摘要

由於浮動式光達為近年新興的遠距遙測技術，其利用雷射都普勒效應所量測的數據尚未受到國際規範機構的認證，本研究參考國際組織Carbon Trust於2013年11月發布浮動式光達在商業化前需達成的三個重要階段，透過浮動式光達的系列試驗與驗證過程，包括水槽試驗、陸域試驗、港內試驗、近岸試驗與離岸試驗，目的是提高量測數據的可信度與準確度；透過量測的風場數據進行風場特性的場址分析與季節分析，包括風速、風向、紊流強度、陣風和風切係數，根據其分析結果，可知浮動式光達優異的性能進行風場量測，對於台灣未來發展離岸發力發電具有極大的潛力與助益，並建立國內首次浮動式光達系列試驗與驗證的典範。

Because the floating LiDAR is the state-of-the-art remote-sensing technology using the laser-Doppler shifted effect, there is still no international formal certification of the measured data. In this study, we conducted a series of test and validation processes based on the three important stages before commercial of the floating LiDAR released by not-for-dividend company Carbon Trust on Nov. 2013, including flume test, land test, harbor test, nearshore test, and offshore test. The objective is to verify the confidence and accuracy of measured data. Also, the site and seasonal analysis of wind characteristics were investigated, including wind speed, wind direction, turbulence intensity, gust, and wind shear. The results show the great capability and performance of the floating LiDAR and have a promising potential and influence to the offshore wind industry of Taiwan. The goal is to set the example for the series of tests and validation of floating LiDAR in Taiwan.
