中文摘要 移動通信系統設備已廣泛運用在日常生活中,其中最大優勢為其便利性、穩定性及擴充性,如能依現有移動通信系統架構(GSM System),透過低空無人飛行載具搭載中繼平台將其訊號延伸,除有助於迅速恢復通信盲區內之通聯網絡,屆時亦可解決地面各種因災害而產生的通信阻斷。就軍事方面而言,更可協助各種地面移動武器系統,建立持續與穩定的通信架構,減少遭受地形遮障所產生的通信死角。

研究初期首先瞭解現有GSM900 系統工作模式、通信中繼器的作業分析與無人飛行載具的飛行限制與條件。隨後著手分析適合寛頻通信、空對地架構之「低空載具高效能天線」,並與教授研討其配置方式與可行性。

研究過程區分可行性評估,針對通連距離與接收靈敏度計算。接著依照無人飛行載具搭載限制條件,蒐集製成與實驗材料,著手進行構型計算與施作。而最終實驗階段採(室內)電磁波無反射室與(室外)飛行試驗場,進行2 階段實地、實裝測試,並透過實驗過程紀錄最佳的參數與數據,作為後續精進的依據。
英文摘要 The mobile communication system, whose most remarkable advantages are convenience, stability, and extensibility, has been widely applied in daily life. Depending on the structure of the mobile communication system, the signals can be stretched through the UAV with the repeater platform, which can help proving the connection rapidly between the communication dead zones. In the military respect, the mobile communication system can help various kinds of weapon system to construct a communication structure which is persistent and stable.
The first step of the research is to understand the working mode of GSM900, the analysis of communication repeater equipment and the aviation limitations and conditions of UAV. And then analyze the broadband communication and sky-to-ground structure which is suitable to the low
altitude & high performance antenna, and discuss with the professor about the feasibility.
There are three stages in the research: the feasibility evaluation, connection distance and the calculation of receive sensitivity. Then follow the limitations and conditions of UAV to launch the experiments. The final part of the experiment use 2-stage tests which are shielded RF Anechoic chamber and aviation experimental region, and record the best parameters and data in the experimental process as a reference for further modification.
