全球導航衛星系統遙測技術應用於地表探測近年來蓬勃發展，包含偵測海面高度、地表植被含水量、海洋風場、冰層厚度等皆是其應用範疇。本篇論文以GNSS反射訊號接收儀接收經由海面反射衛星訊號之飛行測試實驗為基礎，針對該飛行測試實驗所獲得的資料進行處理，分為兩個部分：第一部分為反射訊號鏈路分析，主要將飛行測試之接收機相關參數、衛星相關參數以及反射面參數等代入一套完整的反射訊號鏈路分析流程，該流程最終計算出在該反射情境下所接收之訊雜比，並且以飛行測試實驗的延遲都卜勒映射訊雜比進行比對、驗證。
第二部分為針對該實驗所獲得的延遲都卜勒映射進行資料校正，由於接收機接收衛星反射訊號並處理成延遲都卜勒映射時會受到外部環境干擾與儀器本身之雜訊干擾，因此針對該接收機提出資料校正的流程，最終將以記數表示之延遲都卜勒映射轉換成以瓦特表示之延遲都卜勒映射，轉換過後的結果即為濾除雜訊後的延遲都卜勒映射，之後再將其代入風速反演流程，計算出該實驗當下海洋反射面的風速，並且利用ASCAT的風場資料進行比對、驗證。

The technique of Global Navigation Satellite System Reflectometry (GNSS-R) for remote sensing has been flourishing in recent year, of which application, for example, are the altimetry, soil moisture retrieval, wind field retrieval on the ocean surface, and snow depth estimation. Based on the flight test experiment of GNSS-R receiver conducted in this thesis, the data obtained after the flight test experiment is extracted for post processing. The content of this thesis mainly consists of two parts. The first part is the link budget analysis for the GNSS signal after being reflected from the ocean. The input data comes from the GNSS-R receiver flight test experiment, such as receiver related parameters, GNSS satellite related parameters, and reflection surface related parameters. After the procedure implementation, the output of the link budget analysis for reflected GNSS signal is the signal to noise ratio which is compared and verified with the delay Doppler map (DDM) signal to noise ratio value from the GNSS-R receiver.

The second part is the data calibration. The input data comes from the DDMs generated by the GNSS-R receiver during the flight test experiment. Because of the fact that the GNSS signal received by the receiver and generated into the DDM is subject to the external environment noise and the interior instrument noise, therefore, the calibration procedure for the GNSS-R receiver is proposed. The ultimate result is the calibrated DDM in Watt converted from the DDM in count before calibration. The calibrated DDM can further be used for wind retrieval algorithm in this thesis to obtain the wind speed on the ocean surface. The result of wind retrieval is compared and verified with the Advanced Scatterometer (ASCAT) data product on the date of the flight test experiment.
